Which molecule serves as the template for protein synthesis?

• A. mRNA
• B. DNA
• C. tRNA
• D. rRNA

Answer: (A)

Protein synthesis uses mRNA as the template because the genetic code is first copied from DNA into messenger RNA, which then travels to ribosomes to be read during translation. The ribosome reads mRNA codons and, with the help of transfer RNA delivering the corresponding amino acids, builds the polypeptide chain. DNA stores the genetic information but is not the direct template used in translation. tRNA acts as the adaptor, bringing specific amino acids to match each codon, while rRNA forms the core of the ribosome and catalyzes the peptide bonds that link the amino acids. So mRNA is the template used in the process of translating genetic information into a protein.
