Question

Plasmids are preferred as vehicle DNA because they

• A. denature easily
• B. can be easily detected at time of cloning experiments
• C. multiply along with bacterial chromosome
• D. can be easily isolated and introduced

Answer 1

The correct option is D can be easily isolated and introduced

A plasmid is a small DNA molecule within a cell that is physically separated from a chromosomal DNA and can replicate independently. plasmid serves as a vehicle for genes of interest. They are easy to identify, isolate and introduce.

So, the correct option is 'can be easily isolated and introduced'.
