Question

question 6 of 10
a codon contains a triplet code. which of the following is true of this code?
a. the three nucleotides of a codon carry information to make a single amino acid.
b. the three nucleotides of a codon carry information to make a single protein.
c. the three polypeptides of a codon carry information to make a single protein.
d. the three polypeptides of a codon carry information to make a single amino acid.

Explanation:

A codon is a triplet of nucleotides. During translation, each codon (three - nucleotide sequence) in mRNA corresponds to a specific amino acid. Proteins are made up of multiple amino acids linked together as polypeptides. So, a single codon (three nucleotides) codes for a single amino acid, not a protein (which is a large molecule made of many amino acids) and codons are made of nucleotides, not polypeptides.

Answer:

A. The three nucleotides of a codon carry information to make a single amino acid.
