The number of code words for amino acid varies from one for methionine and tryptophan to six for arginine, leucine, and serine. (i-sis.org.uk)
d-Limonene, γ-terpinene, proline (Pro), arginine (Arg), and serine (Ser) contributed the most to the flavors of citrus, herb, and sweet citrus based on odor and taste activity value analysis. (bvsalud.org)
Yet Serine (S) and Leucine (L) also have 6 codons. (flywheelsites.com)
Amino acid14
5-8 The bi-allelic polymorphism, either a T or C in the DNA sequence at position +869 (relative to the major transcription start site), changes the amino acid at codon 10 from leucine to proline. (bmj.com)
Similarly, the bi-allelic polymorphism, either a G or C at position +915, results in the amino acid at codon 25 being either arginine or proline. (bmj.com)
Rare Amino Acid Challenge to the Origin of Life Excerpt: Granted that on early Earth arginine and lysine are either totally missing or available only at such extremely low abundance levels as to be irrelevant, and recognizing that arginine-and-lysine-containing proteins are essential for the crucial protein-DNA interactions, naturalistic explanations for the origin of life are ruled out. (uncommondescent.com)
The first two positions of the codon are fixed for a particular amino acid while the third position is said to 'wobble', allowing for alternate code letters, hence two or more codons for most amino acids. (i-sis.org.uk)
Each amino acid is encoded for by 3 nucleotides termed a codon. (addgene.org)
As there are only 20 natural amino acids and 64 codon combinations each amino acid is encoded for by multiple codons. (addgene.org)
Arginine is an amino acid naturally produced by our bodies and plentiful in the fish, meat, and nuts that we eat. (scitechdaily.com)
One successful method was increasing the amount of amino acid transporter proteins so that the cells could more efficiently take up arginine and other amino acids. (scitechdaily.com)
This code either matches an amino acid or tells the cell when it is time to start (start codon) or stop (stop codon) adding amino acids to a polypeptide chain. (biologydictionary.net)
My hunch was that the amino acid arginine (Aka: "Arg" or "R) seems to be showing frequent association with pathogenicity. (flywheelsites.com)
Disproportionally low are things that make sense, such as methionine (M), which only has one codon (ATG) instructing for insertion of this amino acid in a sequence. (flywheelsites.com)
If codon dosage was key to variant proportioning, then these should have been seen at least 2x more than M and W, so perhaps something more than codon dosage mediates amino acid choice in creating pathogenic variations. (flywheelsites.com)
Yet no other amino acid in the STXBP1 pathogenics has this changling capacity, so why is it that arginine is at high proportion in the assigned pathogenics? (flywheelsites.com)

Tryptophan2
We have studied the effects of mutations of this glycine to arginine, tryptophan, or alanine on the interaction of human alkyltransferase with O 6 -benzylguanine using direct determination of the amount of activity remaining after incubation with various concentrations of the inhibitor and measurement of the rate of production of [8- 3 H]guanine from O 6 -benzyl[8- 3 H]guanine as assays.

Synonymous Codons3
All current GM crops use protein coding genes from bacteria that have been altered by introducing synonymous codons, replacing plant-preferred codons for the bacterial codons in order to enhance the production of protein from the transgenes. (i-sis.org.uk)
The synonymous codons were assumed to be neutral and to have no effect on the transgenic proteins, and presumed to be safe [2] ( Bt Toxins in Genetically Modified Crops: Regulation by Deceit , SiS 22). (i-sis.org.uk)
Synonymous codons in the oncogenes of the rabbit papillomavirus increased oncogenicity and immunogenicity [7]. (i-sis.org.uk)
Furin cleavage site3
When I first saw the furin cleavage site in the viral sequence, with its arginine codons, I said to my wife it was the smoking gun for the origin of the virus," said David Baltimore, an eminent virologist and former president of CalTech. (blogspot.com)
So the only difference between Covid-19 and RaTG13 which involves more than 3 nucleotides (more than one complete 3 letter Codon) is the Furin Cleavage Site which involves 12 nucleotides and parts of 5 Codons (15 nucleotides). (coldwelliantimes.com)

Glycine2
However, alteration of glycine 160 to arginine drastically reduced the inactivation by O 6 - benzylguanine with at least a 20-fold increase in the ED 50 value and a similar reduction in the production of guanine whether inactivation was carried out in the absence or presence of DNA. (psu.edu)

In combing through the Cancer Genome Atlas, Hsu documented thousands of instances of codon mutations, but one stood out amongst all cancers: arginine codons, which were lost during mutations far more than they should've been. (scitechdaily.com)
In another experiment, Hsu found an increase in the number of mutations towards codons that produce amino acids that were more abundant in the environment of the cancer cells. (scitechdaily.com)

Essentially all commercial GM crops contain bacterial genes with codons altered to enhance the expression of transgenes in plants. (i-sis.org.uk)
GENBANK1
Thus, for the convenience of people reading GenBank records, the genetic code tables shown here use T instead of U. The initiator codon - whether it is AUG, CTG, TTG or something else, - is by default translated as methionine (Met, M). The possible intiator codons are marked as 'M' in the second ('Starts') row of the translation tables. (nih.gov)

On a cellular level, arginine plays a role in a variety of processes, from nitrogen waste disposal to protein synthesis. (scitechdaily.com)
Our findings pave the way for optimizing biocompatible peptides to alter hyaluronan gels' properties efficiently and also explain why hyaluronan-protein interaction typically involves positively charged arginine-rich regions also capable of forming hydrogen bonds and non-polar interactions. (bvsalud.org)
A stop codon is a genetic code that signals the end of protein manufacturing inside the cell, like a period at the end of a sentence. (biologydictionary.net)
When we think of the word codon we should immediately think of protein synthesis and our DNA. (biologydictionary.net)

The cell line CTR contained a 4-base pair deletion at codons 219/220 in exon 6 with resultant frame shift and premature termination in exon 7. (nih.gov)
Stop8
The genetic code is made up of 64 three letter codons (code words) for twenty amino acids (61 codons) plus words for translation start and stop. (i-sis.org.uk)
AGA and AGG were thought to have become mitochondrial stop codons early in vertebrate evolution ( Osawa, Ohama, Jukes & Watanabe 1989 ). (nih.gov)
A stop codon tells the ribosome and transfer DNA that the process can stop and the new polypeptide chain can be released. (biologydictionary.net)
Without stop codons, an organism is unable to produce specific proteins. (biologydictionary.net)
Both start and stop codons in DNA and RNA, just as their names suggest, provide start and stop instructions that regulate the length of a polypeptide chain. (biologydictionary.net)
All codons are made up of three nucleotide bases and named according to the order of these bases - for example, the stop codon TAG tells us that it is made up of thymine, followed by adenine, followed by guanine. (biologydictionary.net)
