Question

Which of the following functions is NOT attributed to non-genetic RNA?

• A. Acts as messenger to carry information from nucleus to cytoplasm
• B. Transports amino acids from cytoplasm to ribosomes for protein synthesis
• C. Exist as components of ribosomes
• D. Acts as the hereditary material in many organisms

Answer 1

The correct option is D Acts as the hereditary material in many organisms

RNA is classified into two major categories- genetic RNA and non-genetic RNA. Genetic RNA is the type of RNA that acts as the hereditary material in many organisms such as viruses. Non-genetic RNA further, is of three types- rRNA, tRNA and mRNA. rRNA or ribosomal RNA is a component of ribosomes, and plays various roles during different stages of protein synthesis. tRNA or transfer RNA carries amino acids from the cytoplasm to the ribosomes during protein synthesis. mRNA or messenger RNA acts as a messenger to carry genetic information from the nucleus to the cytoplasm. Although rRNA, tRNA and mRNA play various roles during different stages of protein synthesis, they don’t directly get inherited as hereditary material by organisms.
