Question

A ribozyme is an:

Options

• Exception to the one gene-one RNA molecule axiom.

• Enzyme that adds the 5 caps and poly (A) tail to mRNA.

• Example of Reassignment of protein domains caused by RNA splicing.

• RNA molecule that functions as an enzyme.

Answer 1

Enzyme that adds the 5 caps and poly (A) tail to mRNA.

Explanation:

A ribozyme is an enzyme that catalyses a chemical reaction using ribonucleic acid (RNA). In a similar fashion to protein enzymes, ribozymes catalyse certain reactions. Ribozymes, also known as catalytic RNA, are present in the ribosome, where they combine amino acids to build protein chains.
