Question

Telomerase is an enzyme which is a

• A. RNA
• B. Ribonucleoprotein
• C. Simple protein
• D. Repetitive DNA

Answer 1

The correct option is B

Ribonucleoprotein

The correct option is B

Explanation of the correct option:

1. Telomerase is an enzyme that adds a particular sequence TTAGGG to the end of the nucleotide of a chromosome.
2. It is also known as telomerase transferase.
3. It is made up of ribonucleoprotein.

Explanation of the incorrect options:

Option A:

1. RNA is a ribose nucleic acid present in several organisms as a genetic material.
2. It contains ribose as a sugar.

Option C:

1. Proteins are polymers of amino acids.
2. Amylase and lipase are examples of some proteinaceous enzymes.

Option D:

1. Repetitive DNA sequences are repeated may times in a particular nucleotide sequence.
2. They are the same sequences having multiple copies.

Final answer: Telomerase is an enzyme which is a ribonucleoprotein.
