Question

Ribozymes are
A. RNA acting as enzymes
B. Antibody acting as enzymes
C. Ribosomes acting as enzymes
D. None of the above

Answer 1

Hint: Ribozymes are the combination of RNA protein complex and catalytically active RNA molecules. It is found in the genome of the species. It is defined as the enzymatic activity and ribonucleic acid nature. It has the ability to catalyze the biochemical reaction. This function is done by protein. It is the first molecule to precede catalytic property. Ribozymes are also found in the ribosome where it joins with the amino acid to form protein chains.

Complete answer:
Option A: Enzymes are the catalyst in the biological reaction. Catalyst is used for speeding up the process. So enzymes help to speed the biological process and metabolic reactions. Nucleic acid is acting as an enzyme. This is called the Ribozymes. This Ribozyme is the molecule of RNA. So here RNA is acting as an enzyme. Option A is correct.
Option B: Abyzyme is produced by the antibody and enzyme. It is called the catalytic antibody. It is the monoclonal antibody which has catalytic activity. Antibodies are also called as the protein source. Option B is incorrect.
Option C: Ribozymes are the protein. It is not the enzyme because it is the molecule of RNA. So Ribozymes are part of RNA. It performs RNA transesterification and RNA cleavage. Option C is incorrect.
Option D: Ribozymes in the RNA act as enzymes. Option D is incorrect.

Hence, Option A is the correct answer.

Note:
Hammerhead Ribozymes is the RNA module that catalyzes the reversible cleavage and joining reactions at specific places in the RNA molecule. This Ribozymes is performs three important functions. It acts as therapeutic agents and bio sensors. It used in functional genomics and gene discovery. Inverse genomics is used to find the function of genes. Ribozymes act as the bio sensor while oligonucleotide regulates the Ribozymes.
