Question

what is the primary role of mrna in protein synthesis?
catalyzes peptide bond formation
brings amino acids to the ribosome
forms the ribosome
carries genetic code from dna to ribosome

Explanation:

1. Analyze each option:

• "Catalyzes peptide bond formation": This is the role of ribosomal RNA (rRNA) or ribozymes, not mRNA.
• "Brings amino acids to the ribosome": Transfer RNA (tRNA) is responsible for bringing amino acids to the ribosome.
• "Forms the ribosome": Ribosomal RNA (rRNA) and proteins form the ribosome, not mRNA.
• "Carries genetic code from DNA to ribosome": Messenger RNA (mRNA) is transcribed from DNA and carries the genetic information (code) to the ribosome, where protein synthesis occurs.

Answer:

D. Carries genetic code from DNA to ribosome
