Answer 2

Answer:

d) Thymine is not a component of RNA.

Explanation:

The RNA molecules are single stranded nucleic acids composed of nucleotides. RNA stands for Ribo-Nucleic Acid.

RNA nucleotides contains three components :-

• A Nitrogenous Base
• A Five-Carbon Sugar
• A Phosphate Group

RNA nitrogenous bases include Adenine (A), Guanine (G), Cytosine (C) and Uracil (U).

NOTE :- In DNA (Deoxyribonucleic Acid), the nitrogenous bases are :-

1. Adenine
2. Guanine
3. Cytosine
4. Thymine

BACK TO THE QUESTION

The question talks about which of the options is not a component of RNA. On carefully examining the options we see that Option (d) Thymine is not a component of RNA so the answer is option d) Thymine.

[Thymine is not a component of RNA but it is a component of DNA :) ]
