Question

Which of the following is the final product of a gene?

• A. A polypeptide
• B. An RNA only
• C. Either polypeptide or RNA
• D. A nucleotide only

Answer 1

The correct option is A A polypeptide

DNA is the master which gives instructions to the cell for building proteins which are long chains are polypeptides.

The process in which the genetic message in DNA is copied into mRNA is called transcription. This mRNA is used to make protein molecules by the process of translation. This is the central dogma of protein synthesis. Hence the final product of a gene is a polypeptide. Thus, the correct answer is option A.
