Question

2 each set of three nitrogenous bases that codes for an amino acid on mrna is known as a a rna b codon c protein d nucleotide

Explanation:

• RNA (Ribonucleic Acid) is a nucleic acid, not a set of three bases coding for an amino acid.
• A codon is defined as a sequence of three nitrogenous bases on mRNA that codes for a specific amino acid.
• A protein is a large biomolecule made up of amino acids, not a three - base sequence.
• A nucleotide is a building block of nucleic acids (like RNA and DNA), consisting of a nitrogenous base, a sugar, and a phosphate group, not a three - base sequence coding for an amino acid.

Answer:

B. codon
