Question:
Assertion (A): Plasmids are autonomously replicating circular extra-chromosomal DNA.
Reason (R): Plasmids are usually present in eukaryotic cells.
Assertion (A): Plasmids are autonomously replicating circular extra-chromosomal DNA.
Reason (R): Plasmids are usually present in eukaryotic cells.
Reason (R): Plasmids are usually present in eukaryotic cells.
Show Hint
Plasmids are essential tools in molecular biology for gene cloning and expression studies due to their ability to replicate independently.

- Both (A) and (R) are true and (R) is the correct explanation of (A)
- Both (A) and (R) are true and (R) is not the correct explanation of (A)
- (A) is true, but (R) is false
- (A) is false, but (R) is true
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Plasmids are autonomously replicating circular DNA molecules found in prokaryotic cells, not eukaryotic cells. These plasmids are widely used as vectors in genetic engineering.
