Molecular clocks use rates of mutation to measure evolutionary time.Mutations add up at a fairly constant rate in the DNA of species that evolved from a common ancestor. The more mutations that happened in each lineage, the greater is the differences between these lineages.

Answer:
(A). mRNA.
Explanation:
During protein synthesis, information present in DNA as triplet codons gets transferred to mRNA molecule, by the process of transcription. The mRNA than gets transported to the cytosol, where it associates with ribosomes.
Ribosomes are known as protein factories of the cells as they provide platform for translation. During translation, information present in mRNA is used to translate polypeptide chain or protein as each codon codes for a specific amino acid.
Thus, the correct answer is option (A).
