There are three codons that do not code for any amino acids: the stop codons. These are TAG, TAA, and TGA (in DNA, not RNA).
61 codons specify the amino acids used in proteins and 3 codons (stop codons) signal termination of growth of the polypeptide chain...so 64 total
1. the start codon 2. 150 codons, 1 for each amino acid 3. the stop codon The total number of different codons is 64...if this question is asking about unique codons used the answer will depend on which amino acids are in the peptide.
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.
Each codon codes for a specific amino acid, which is a building block of proteins. The sequence of codons in mRNA determines the sequence of amino acids in a protein. There are 64 possible codons, with 61 coding for amino acids and 3 serving as stop codons to signal the end of protein synthesis.
There are 64 possible different codons (4 nucleotides in a sequence of 3), including 61 codons that code for amino acids and 3 stop codons.
There are 64 codons (3-base code) that represent 20 amino acids and 3 stop signals. Click on the related link to see a table of DNA codons and the amino acids for which they code.

61 codons specify the amino acids used in proteins and 3 codons (stop codons) signal termination of growth of the polypeptide chain...so 64 total
The ratio of codons to amino acids is typically 3:1, as each codon consists of three nucleotides that correspond to one amino acid in the genetic code. However, there are 64 possible codons (including stop codons) but only 20 standard amino acids, which means some amino acids are encoded by multiple codons. This redundancy in the genetic code helps to minimize the effects of mutations.
The answer is nine because one codon has 3 letters.Improved AnswerThe above answer is completely incorrect. The question is how many codons are necessary to specify three amino acids, not bases (letters). As my original answer (which was removed by the previouis contributor) pointed out, each amino acid requires one codon to specify it, so the basic answer is, three codons are necessary to specify any three amino acids. However, if the questioner had in mind how many codons are necessary to specify a polypeptide consisting of three amino acids, the answer is five, because, in addition to the three codons necessary for the amino acids, a start codon of AUG (on the mRNA transcript), and one stop codon (UAG, UGA,or UAA on the mRNA transcipt) are also needed. So, in this sense, five codons are needed to specify a polypeptide of 3 amino acids.Improved Answer: The answer is 9. ^ fail XD
To make 3 amino acids, you would need at least 9 bases. This is because each amino acid is encoded by a sequence of 3 bases called a codon. So, 3 amino acids would require 3 codons, which would be 9 bases in total.

tRNA. Transport ribonucleic acid, it is a 3 loop structure that brings specific amino acids to the ribosome. Has anticodons specific to the codons.
DNA codons are sequences of three nucleotides that correspond to specific amino acids or stop signals during protein synthesis. There are 64 possible codons, including 61 codons that encode for amino acids (like AUG for Methionine and UUU for Phenylalanine) and 3 stop codons (UAA, UAG, and UGA). Codons are usually represented by their corresponding mRNA sequence, as DNA is transcribed into mRNA during protein synthesis. In summary, the codons are named based on the amino acids they encode or their function as stop signals.
