Explanation:
Detailed explanation-1: -The nucleotide sequence of a gene, through the medium of mRNA, is translated into the amino acid sequence of a protein by rules that are known as the genetic code.
Detailed explanation-2: -So, the correct answer is ‘ mRNA’.
Detailed explanation-3: -At its heart, the genetic code is the set of “rules” that a cell uses to interpret the nucleotide sequence within a molecule of mRNA. This sequence is broken into a series of three-nucleotide units known as codons (Figure 1).
