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.

How many codons are needed to specify three amino acids 6 or 9?

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


How many codons are neede to specify two amino acids?

In order to create two amino acids, you would need two codons, which is 6 bases (Adenine, Guanine, Thymine, or Cytosine) because a codon is a group of three bases.


What 3 codons do not carry amino acids?

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).


How many codons would be needed if a bacterial protein contains 150 amino acids?

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.

The triplet code means that 64 codons translate into only 20 amino acids. What are the additional 44 codons used for?

The triplet code means that 64 codons translate into only 20 amino acids. The additional 44 codons are not used for anything, but they are rather a redundancy in the code.
