Question

How many base pairs are present in a segment of m-RNA having 100 nucleotides?

• A. 100
• B. 50
• C. 0
• D. 25

Hint:

Single-stranded nucleic acids like {m-RNA have no base pairs}.

Answer 1

The Correct Option is C

Step 1: Understanding the structure of m-RNA.
m-RNA is a single-stranded nucleic acid molecule involved in protein synthesis.

Step 2: Concept of base pairing.
Base pairing occurs only in double-stranded nucleic acids such as DNA. Since m-RNA is single-stranded, it does not contain base pairs.

Step 3: Conclusion.
Thus, a segment of m-RNA having 100 nucleotides contains 0 base pairs.
