Answer 2

Answer:

RNA has A-U base pairing.

Explanation:

What is RNA?

• RNA means ribonucleic acid.
• It is essential in protein synthesis.
• RNA has a single helical structure.
• In RNA structure, two types of nitrogen bases are present, purine and pyrimidine.
• Purine contains guanine and adenine base pairs, while pyrimidine contains cytosine and uracil base pairs.
• Guanine binds with cytosine via triple hydrogen bonds (G ≡ C), while adenine binds with uracil via double hydrogen bonds (A = U).

What is DNA?

• DNA means deoxyribonucleic acid.
• It is essential for genetic, immunological and structural aspects.
• It has a double helical structure.
• In DNA structure, similar to RNA, purine and pyrimidine nitrogen bases are present.
• Purine contains guanine and adenine base pairs while, in the case of DNA, pyrimidine contains adenine and thymine base pairs.
• Guanine binds with cytosine via triple hydrogen bonds (G ≡ C), while adenine binds with thymine via double hydrogen bonds (A = T).

This is the key difference between DNA and RNA nitrogen bases.

G ≡ C pairing and P-S-P-S backbone are the same in both DNA and RNA.

So, the correct option is (a) A -U base pairing.
