Of the 64 codons, the three that do not code for amino acids are stop codons.
The stop codons are:
TAG in DNA (UAG in mRNA)
TAA (UAA)
TGA (UGA)
They signify the end of the gene, i.e. the end of the segment to be transcribed and translated.
the answer is.. Stop signals. B. stop
stop
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
Nucleutoides.
The linear sequence of codons on mRNA determines the linear sequence of amino acids in a polypeptide.
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.
B. stop
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.
The Code 'alluded to' above is called - and is also known as - The Genetic Code.
mRNA
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).
Start and stop codons
Nucleotides are merely the building blocks of nucleic acids like DNA and RNA. The specific order of these nucleotides are read in triplet form (AAC, ATA, etc.) as codons (which code for amino acids), and the combinations of these codons make up genes (which code for proteins).

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.
