Question

Which of the following is not a function of RNA?

• A. It is the genetic material in several bacteria
• B. It is the genetic material in some viruses
• C. It is a constituent of ribosomes
• D. It acts as a catalyst for some biochemical reactions

Answer 1

The correct option is A It is the genetic material in several bacteria

RNA is the genetic material for many viruses. Though bacteria show the presence of RNA, it does not act as the genetic material in them. Bacteria have DNA as genetic materials. A type of RNA known as rRNA (ribosomal RNA) is a major constituent of ribosomes. RNA shows catalytic activity in some biochemical reactions and in such cases is referred to as the ‘ribozyme.’
