The term 'recombinant DNA' refers to

A

DNA of the host cell

B

DNA with a piece of foreign DNA

C

DNA with selectable marker

D

DNA with more than one recognition sites

Text Solution

Verified by Experts

The correct Answer is:

B

After cutting the source DNA and the vector DNA with a specific restriction enzyme, the cut out 'gene of interest' form the source DNA and cut vector with space are mixed and ligase enzyme is added. This results in the formation of rDNA or hybrid DNA or chimeric DNA/
