What else can I help you with?
All amino acids are specified by only one codon?
No. Some are specified by only one codon eg. methionine and tryptophan. But some have more than one codon eg. threonine.
True or false A codon signifies either a specific amino acid or a stop signal?
It is false that all amino acids are specified by only one codon. The codon is simply the language that is used to relay information concerning the messenger ribosomal nucleic acid.
What is the number of codons that actually specify amino acids is?
61. there are 64 total codon arrangements. However three of those (UAA, UAG, UGA) are STOP codons and in turn do not call for the tRNA to bind a protein. Rather, these 3 codons call for termination of translation. The START condon in RNA is UAG, with calls for the amino acid (Met'). It is important to remember that even though there are 61 codons that call for amino acids, only 20 amino acids are available. This means that more than one codon can call for the same amino acid which brings about the REDUNDANT characteristic of codons. However they are NOT AMBIGUOUS, meaning that a codon cannot call for several different amino acids. Serveral codons can call for the same amino acid, but each codon can only call for ONE specific amino acid.
Why are there 64 codons but only 20 amino acids in the genetic code?
The genetic code has 64 codons because it is made up of combinations of 3 nucleotides, which can create 64 different combinations. However, there are only 20 amino acids in the genetic code because some amino acids can be coded for by more than one codon.
What amino acid is encoded by the initiation codon AUG?
The amino acid that is encoded by the initiation codon AUG is methionine. It is the only amino acid which is specified by just one codon.
Are amino acids only represented by one codon?
No. Amino acids are not always represented by only one codon. Several may code for one amino acid.
What amino acid is represented by only one codon?
There are two amino acids that only correspond to one codon:Tryptophan whose codon is UGGMethionine whose codon is AUG
What two amino acids are represented with only one codon?
They are triptopan and methionine.Codons are UGG and AUG respectively.
There can only be one what for every codon?
There can only be one amino acid for every codon. Tryptophan and Methionine are the types of amino acids that correspond to codon.
Which amino acids have only one codon?
There are two different amino acids that only have one codon. Methionine thatâ??s DNA codon is ATG and Tryptophan thatâ??s DNA codon is TGG.
All amino acids are specified by only one codon?
No. Some are specified by only one codon eg. methionine and tryptophan. But some have more than one codon eg. threonine.
What are the amino acids on the codon table?
Each codon codes for only one amino acid, or a codon is a start or stop codon, but no codon codes for more than one amino acid.
For any one codon there can be only one what?
For any one codon, there can be only one amino acid that it codes for. Each codon in the genetic code corresponds to a specific amino acid, ensuring that the correct sequence of amino acids is produced during protein synthesis.
Which amino acid was never coded for?
Several amino acids are not coded for in biology. 20 are. The two standard amino acids are selenocysteine and pyrrolysine. Then there are the numerous non-standard amino acids, which include hydroxyproline and selenomethionine.
How many amino acids does each condon code for?
No they are not. For a codon, there are 4^3 = 64 codon combinations, but only 20 [common] amino acids. The 4 represents the 4 nitrogenous bases, and the ^3 represents the arrangement into a codon (3 bp). An example of an amino acid that is specified by more than one amino acid is Alanine, which is specified by any of the following combinations: GUU, GUC, GUA, GUG. Because most amino acids have more than one codon, the genetic code is called "degenerate".
Do stop codon have an amino acid?
A stop codon (UGA, UAA, UAG) only codes for a stop. No amino acid results from a stop codon.
Is it possible for mutations to go unnoticed in mRNA?
Yes it is. There are more triplet codons than there are [biologically active] amino acids that need to be represented in the Cell, so that there is some duplication of codon/amino acid 'alignment'. This occurs only in the third base position of the triplet codon - the 'wobble base' position - so if a mutation occurred in the wobble (third) position and the codon was one of the few that was not alone in its amino acid specificity this mutation would go unnoticed.
