Question

Sequence of amino acid in polypeptide chain is determined by

• A. r RNA
• B. sn RNA
• C. n RNA
• D. m RNA

Answer 1

The correct option is D m RNA

• Messenger RNA(mRNA) is a large family of RNA molecules that convey genetic information from DNA to the ribosome, where they specify the amino acid sequence of the protein products of gene expression.
• RNA polymerase transcribes primary transcript mRNA into processed, mature mRNA.
• Hence, the Sequence of amino acid in the polypeptide chain is determined by m RNA.
• So, the correct answer is ' mRNA'.
