Question

Assertion (A): Plasmids are autonomously replicating circular extrachromosomal 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 play a vital role in genetic engineering for cloning and gene expression studies.

Answer 1

The Correct Option is C

While plasmids are self-replicating circular DNA, they are prevalent in prokaryotic cells, such as bacteria, rather than eukaryotic cells.
