Question

Which of the following is not an RNA?

• A. m-RNA
• B. d-RNA
• C. t-RNA
• D. r-RNA

Hint:

The three major types of RNA are: m-RNA (Messenger RNA) t-RNA (Transfer RNA) r-RNA (Ribosomal RNA) These together participate in the process of protein synthesis.

Answer 1

The Correct Option is B

Step 1: List the three types of RNA.
The three functional RNA types are: mRNA (messenger), tRNA (transfer), and rRNA (ribosomal). These are all real RNA molecules involved in protein synthesis.

Step 2: Identify the false option.
d-RNA is not a recognised type of RNA. The prefix 'd' applies to DNA (deoxyribonucleic acid), not RNA. \[ oxed{d ext{-RNA}} \]
