Question

A sequence of three nucleotide bases on mRNA that refers to a specific amino acid.

Answer 1

A sequence of three nucleotide bases on mRNA that corresponds to a specific amino acid is called a **codon**. Each codon in the mRNA sequence is translated into an amino acid during the process of protein synthesis. The genetic code includes 64 possible codons, which are made up of combinations of the four nucleotide bases (adenine, uracil, cytosine, and guanine), and they specify the 20 different amino acids used to build proteins, along with start and stop signals for translation.
