Question

Identify the incorrect statement about Ribozyme and Abzyme from the following?

• A. Both are enzymes
• B. Both are apo-enzymes
• C. RNA and protein respectively
• D. Able to hydrolyse phosphodiester and peptide bonds respectively

Answer 1

The correct option is A

Both are enzymes

Both ribozyme and abzyme are non protein enzymes. In case of a ribozyme, itis a ribonucleic acid (RNA) enzyme that catalyzes a chemical reaction. By nature they are not proteins. Theribozymecatalyses specific reactions in a similar way to that of protein enzymes. Also called catalytic RNA,ribozymesare found in the ribosome where they join amino acids together to form protein chains. And anabzymeis an antibody that expresses catalytic activity. A single molecule of an antibody-enzyme, orabzyme, is capable of catalyzing the destruction of thousands of target molecules. By nature they have protein part in their molecular construction.
