Question

The most unstable RNA is

• A. Messenger RNA
• B. Soluble RNA
• C. Ribosomal RNA
• D. Heterogeneous nuclear RNA

Answer 1

The correct option is D Heterogeneous nuclear RNA

The heterogenous messenger RNA is the most unstable RNA as it formed by the transcription of the complementary strand of DNA and modified into mature m-RNA. The primary transcript RNA is converted into mature RNA. The process includes three major steps, addition of a 5' cap, addition of a 3' poly-adenylation tail, and splicing.

So, the correct answer is 'Heterogeneous nuclear RNA'.
