Answer: Option B) determine the sequence of amino acids in a protein

Explanation:

The messenger RNA (mRNA) molecule carries a seqence of bases that is complimentary to the template strand of DNA.

Hence, instead of thymine, uracil nucleotides exists in the mRNA molecule; while the mRNA is transcribed to the corresponding amino acids.

For instance: a template strand of ACC CGG is transcibed as UGG GCC on mRNA, and translated to an amino acid sequence of Tryptophan and Alanine.
