Question

Assertion (A): Plasmids are autonomously replicating circular extra-chromosomal DNA.
Reason (R): Plasmids are usually present in eukaryotic cells.

• A. Both (A) and (R) are true and (R) is the correct explanation of (A).
• B. Both (A) and (R) are true and (R) is not the correct explanation of (A).
• C. (A) is true, but (R) is false.
• D. (A) is false, but (R) is true.

Hint:

Plasmids are essential tools in genetic engineering for cloning and gene expression studies.

Answer 1

The Correct Option is C

Plasmids are self-replicating circular DNA structures. They are prevalent in prokaryotic organisms, such as bacteria, but absent in eukaryotic cells.
