Question

In recombinant DNA technique, the term vector refers to

• A. Plasmids that can transfer foreign DNA into a living cell
• B. Cosmids that can cut DNA at specific base sequence
• C. Plasmids that can join different DNA fragments
• D. Cosmids that can degrade harmful proteins

Answer 1

The correct option is A Plasmids that can transfer foreign DNA into a living cell

rDNA technology is a technique of transferring a desired gene into another and conbining them for obtaining a sequence that is not found in the genome. Thus a high quality results will be obtained. This is done by using cloning that uses a vector.

Vector is a carrier that is helpful in transferring the genes. Hence the correct option is A.
