RECOMBINANT DNA

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What are the typical characteristics of a cloning vector?
A
Bacterial cells cannot survive without it when grown under certain conditions.
B
It contains restriction sites that allow the insertion of foreign DNA segments.
C
It can replicate in bacterial cells.
D
All of the above.
Explanation: 

Detailed explanation-1: -A cloning vector should possess an origin of replication so that it can self-replicate inside the host cell. It should have a restriction site for the insertion of the target DNA. It should have a selectable marker with an antibiotic resistance gene that facilitates screening of the recombinant organism.

Detailed explanation-2: -A cloning vector is a DNA molecule that has the following characteristics: (1) it is capable of replicating independently of the host chromosome; (2) an organism containing the vector can be grown preferentially; and (3) additional DNA can be inserted into the vector.
