Can You Code?

If someone asks you whether you can code, you probably assume they are referring to computer code. The image in Figure \(\PageIndex{1}\) represents an important code that you use all the time but not with a computer. It's the genetic code, and it is used by your cells to store information and make proteins.

FACIL genetic code logo

What Is the Genetic Code?

The genetic code consists of the sequence of nitrogen bases in a polynucleotide chain of DNA or RNA. The bases are adenine (A), cytosine (C), guanine (G), and thymine (T) (or uracil, U, in RNA). The four bases make up the “letters” of the genetic code. The letters are combined in groups of three to form code “words,” called codons . Each codon stands for (encodes) one amino acid unless it codes for a start or stop signal. There are 20 common amino acids in proteins. With four bases forming three-base codons, there are 64 possible codons. 61 codons are more than enough to code for the 20 amino acids, thus more than one codon codes for a single amino acid. Please find genetic codes in Table \(\PageIndex{1}\) or in appendix 1 .

Reading the Genetic Code

If you find the codon AUG in Table \(\PageIndex{1}\), you will see that it codes for the amino acid methionine. This codon is also the start codon that establishes the reading frame of the code. The reading frame is the way the bases are divided into codons. It is illustrated in Figure \(\PageIndex{2}\). After the AUG start codon (not shown in the image), the next three bases are read as the second codon. The next three bases after that are read as the third codon, and so on. The sequence of bases is read, codon by codon, until a stop codon is reached. UAG, UGA, and UAA are all the stop codons. They do not code for any amino acids.

Characteristics of the Genetic Code

The genetic code has a number of important characteristics:

  • The genetic code is universal. All known living things have the same genetic code. This shows that all organisms share a common evolutionary history.
  • The genetic code is unambiguous. This means that each codon codes for just one amino acid (or start or stop). This is necessary so there is no question about which amino acid is the correct one.
  • The genetic code is redundant. This means that each amino acid is encoded by more than one codon. For example, in the table above, four codons code for the amino acid threonine. Redundancy in the code helps prevent errors in protein synthesis. If a base in codon changes by accident, there is a good chance that it will still code for the same amino acid.
  • Describe the genetic code.
  • Explain how the genetic code is read.
  • Identify three important characteristics of the genetic code.
  • Summarize how the genetic code was deciphered.
  • Is the code depicted in the table from DNA or RNA? Explain your reasoning.
  • Which amino acid does the codon CAA code for?
  • Does UGA code for an amino acid? Why or why not? If so, which one?
  • Look at the codons that code for the amino acid glycine. How many of them are there? What are their similarities and differences from each other?
  • Imagine that you are doing an experiment similar to the one performed by Nirenberg and Matthaei with 20 test tubes, each containing bacterial cell contents and all 20 amino acids, with one type of amino acid labeled in each tube. If you added synthetic RNA containing only the base cytosine, a polypeptide chain consisting of which amino acid would be produced? Explain your answer.
  • True or False. One codon can encode for more than one amino acid.
  • True or False. The codons for tyrosine in plants are the same as ones that encode for tyrosine humans.
  • True or False. The start codon encodes for an amino acid, in addition to its function establishing where the reading frame starts.
  • It depends on the species

  • Overview of translation
  • Translation
  • Impact of mutations on translation into amino acids
  • Codons and mutations

Introduction

Overview: gene expression and the genetic code.

  • In transcription , the DNA sequence of a gene is "rewritten" using RNA nucleotides. In eukaryotes, the RNA must go through additional processing steps to become a messenger RNA, or mRNA.
  • In translation , the sequence of nucleotides in the mRNA is "translated" into a sequence of amino acids in a polypeptide (protein or protein subunit).

Code crackers: How the genetic code was discovered

The triplet hypothesis, doublet code, triplet code, nirenberg, khorana, and the identification of codons.

  • A way to make artificial mRNA molecules with specific, known sequences.
  • A system to translate mRNAs into polypeptides outside of a cell (a "cell-free" system). Nirenberg's system consisted of cytoplasm from burst E. coli cells, which contains all of the materials needed for translation.

Properties of the genetic code

Types of codons (start, stop, and "normal").

  • First, we look at the left side of the table. The axis on the left side refers to the first letter of the codon, so we find C along the left axis. This tells us the (broad) row of the table in which our codon will be found.
  • Next, we look at the top of the table. The upper axis refers to the second letter of the codon, so we find A along the upper axis. This tells us the column of the table in which our codon will be found.

Reading frame

One amino acid, many codons, the genetic code is (nearly) universal, references:, want to join the conversation.

Genetic Code

Synthesizing a protein with the help of the information in RNA is similar to translating a language to another. A four-letter language is translated to 20 letter language during protein synthesis . There should be a specific relationship among the four bases of DNA and sequence of 20 amino acids in the protein.

What is a Genetic Code?

The genetic code can be defined as the set of certain rules using which the living cells translate the information encoded within genetic material (DNA or mRNA sequences). The ribosomes are responsible to accomplish the process of translation. They link the amino acids in an mRNA-specified (messenger RNA) order using tRNA (transfer RNA ) molecules to carry amino acids and to read the mRNA three nucleotides at a time.

Genetic Code Table

The complete set of relationships among amino acids and codons is said to be a genetic code which is often summarized in a table.

Genetic Code Table

It can be seen that many amino acids are shown in the table by more than one codon. For example, there are six ways to write leucine in mRNA language.

Note:  A codon is a sequence of three nucleotides which together form a unit of genetic code in a DNA or RNA molecule.

A key point of the genetic code is its universal nature. This indicates that virtually all species with minor exceptions use the genetic code for protein synthesis.

In other words, genetic code is defined as the nucleotide sequence of the base on DNA which is translated into a sequence of amino acids of the protein to be synthesized.

Properties of Genetic Code

Triplet code, non-ambiguous and universal, degenerate code, nonoverlapping code, start and stop codons.

These properties of genetic code are explained below.

A codon or a code word is defined as a group of bases that specify an amino acid. There is strong evidence, which proves that a sequence of three nucleotides codes for an amino acid in the protein, i.e., the code is a triplet .

The four bases of nucleotide i.e, (A, G, C, and U) are used to produce three-base codons. The 64 codons involve sense codons (that specify amino acids). Hence, there are 64 codons for 20 amino acids since every codon for one amino acid means that there exist more than code for the same amino acid.

Commaless code

No room for punctuation in between which indicates that every codon is adjacent to the previous one without any nucleotides between them.

The code is read sequentially in a group of three and a nucleotide which becomes a part of triplet never becomes part of the next triplet.

For example

5’-UCU-3’ codes for Serine

5’-AUG-3’ codes for methionine

Each triplet is read from 5’ → 3’ direction and the beginning base is 5’ followed by the base in the middle then the last base which is 3’. This implies that the codons have a fixed polarity and if the codon is read in the reverse direction, the base sequence of the codon would reverse and would specify two different proteins.

Every amino acid except tryptophan (UGG) and methionine (AUG) is coded by various codons, i.e, a few codons are synonyms and this aspect is known as the degeneracy of genetic code . For instance, UGA codes for tryptophan in yeast mitochondria .

Generally, AUG codon is the initiating or start codon. The polypeptide chain starts either with eukaryotes (methionine) or prokaryotes (N- formylmethionine).

On the other hand,  UAG, UAA and UGA are called as termination codons or stop codons. These are not read by any tRNA molecules and they never code for any amino acids.

The genetic code is non-ambiguous which means a specific codon will only code for a particular amino acid. Also, the same genetic code is seen valid for all the organisms i.e. they are universal.

Exceptions to the Code

The genetic code is universal since similar codons are assigned to identical amino acids along with similar START and STOP signals in the majority of genes in microorganisms and plants. However, a few exceptions have been discovered and most of these include assigning one or two of the STOP codons to an amino acid.

Apart from this, both the codons GUG and AUG may code for methionine as a starting codon, although GUG is meant for valine. This breaks the property of non-ambiguousness. Thus, it can be said that few codes often differs from the universal code or non-ambiguous code.

The Causes of Dyslexia: Neurological and Genetic Factors

This essay about dyslexia explores its nature as a learning anomaly affecting reading, writing, and spelling abilities. It discusses the genetic and neurological factors contributing to dyslexia, such as familial clustering and brain structural differences. Phonological processing deficits are highlighted as a key aspect, impacting word identification and decoding. Additionally, environmental factors can exacerbate dyslexic challenges. Understanding the complex interplay of these factors is crucial for effective intervention and support for individuals with dyslexia, facilitating academic and personal success.

How it works

Dyslexia, a distinct learning anomaly, impairs an individual’s capacity for reading, writing, and spelling, despite normative cognitive abilities and educational access. This neurodevelopmental anomaly manifests as impediments in phonological processing, rendering word identification and decoding arduous tasks. Though widely documented and affecting millions globally, the precise etiology of dyslexia remains a subject of intensive inquiry. Current investigations suggest a multifaceted interplay of genetic and neurological determinants.

Genetics assumes a pivotal role in dyslexia’s genesis. Evidence underscores familial clustering of dyslexia, indicating a hereditary predisposition.

Twin analyses, comparing dyslexia prevalence in identical versus fraternal twins, evince higher concordance rates in identical twins, underscoring genetic influence. Identified genetic loci, such as DCDC2 and KIAA0319, implicated in neuronal migration and cerebral maturation, augment risk rather than guarantee dyslexia onset, highlighting its multifactorial nature.

The neurobiological underpinnings of dyslexia revolve around structural and functional cerebral disparities. Neuroimaging unveils divergences in brain architecture and activation patterns between dyslexic and non-dyslexic cohorts. Notably, reduced left hemisphere engagement, especially in parietotemporal and occipitotemporal domains during reading tasks, characterizes dyslexic cohorts. These regions, pivotal for phonological processing and lexical recognition, elucidate the reading impairments inherent in dyslexia. Furthermore, structural aberrations, like diminished gray matter volume, implicate neural circuitry efficiency and connectivity in reading processes.

At the crux of dyslexia lie phonological processing deficits. Phonological awareness, vital for fluent reading, pertains to discerning and manipulating word sound structures. Dyslexic individuals grapple with segmenting words into phonetic constituents, impeding symbol-sound correspondence. This impediment engenders laborious reading and compromises comprehension, orthography, and lexicon acquisition.

Environmental factors also modulate dyslexia’s phenotypic expression and severity. While not causative, inadequate linguistic exposure, dearth of reading materials, and non-supportive educational milieus exacerbate dyslexic challenges. Timely identification and intervention are imperative, as tailored strategies can ameliorate academic performance setbacks and fortify self-esteem.

Despite elucidated causes and predispositions, dyslexia’s etiological panorama remains intricate and variegated. It warrants recognition that dyslexic manifestations vary across individuals, from mild to severe. Moreover, dyslexia frequently co-occurs with comorbid learning disparities, like attention-deficit/hyperactivity disorder (ADHD), complicating diagnostic endeavors.

In summation, dyslexia ensues from a nexus of genetic and neurological determinants impacting language processing. Genetic susceptibilities and cerebral structural variances set the stage, while environmental influences modulate symptomatology. Grasping these foundational determinants facilitates efficacious interventions and nurturing educational ambiances. By perpetuating research endeavors and comprehending dyslexia’s intricacies, educators, clinicians, and families can furnish comprehensive support to dyslexic individuals, enabling scholastic and personal flourishing.
