Why are plasmids so widely used in recombinant DNA studies?

Abecause they naturally contain much foreign DNA
Bbecause they can be used to transform bacteria
Cbecause it is difficult to insert new genes into them
Dbecause they cannot be cut with restriction enzymes

Verified Answer :

I would guess is B
A: the bacteria contains its DNA
B; when a new gene is added it can transform the bacteria by altering its biochemistry
C:its easy to insert new genes into a plasmid
D: the plasmid is cut with special enzymes

hope that helps

Answer:

Option (B).

Explanation:

Plamids are the extra chromsomal circular DNA present in the bacterias. Plasmid DNA can undergo replication independently to the chromsomal DNA.

Plamids can be used to transform bacteria and used in the molecular techniques. The foreign gene can easily be inserted into the plasmid DNA and used in the formation of recombinant protein.

Thus, the correct answer is option (B).
