What is a Codon

Question

What is a codon?
A) the amino acetyl tRNA synthase that ensures that the correct amino acid is added to the right tRNA
B) the complementarity of DNA and RNA
C) the three- base sequence of mRNA that specifies the addition of a specific amino acid
D) the base sequence of the tRNA that brings the correct amino acid to the ribosome where protein synthesis will take place

Accepted Answer

A codon is a three-base sequence on mRNA that specifies the addition of a specific amino acid during protein synthesis. This means that each codon codes for one specific amino acid, and the sequence of codons determines the sequence of amino acids in the resulting protein.
