Question

Plasmids are suitable vectors for gene cloning because

Answer 1

Answer:

Plasmids are suitable vectors

Answer 2

Answer

• A foreign gene is inserted in T-DNA region of the plasmid.

• The T gene becomes inactive.

• The recombined or cloning vector is now passed into plasmid free bacterium.

• It is allowed to infect the plant or single cells in tissue culture.

• The plasmid with the desired inserted gene passes into variuos parts.

• The inserted gene expresses its effect.

• Agrobacterium tumifaciens normally infects only dicot plants.

• But one with modified nonvirulent plasmid can also cause genetic changes in monocots.
