Vedclass · Answer

(B) recombination vector is a $DNA$ molecule used as a vehicle to artificially carry foreign genetic material into another cell,where it can be replicated and/or expressed. $Agrobacterium$ $tumefaciens$ is a soil bacterium that naturally transfers a segment of its $DNA$,known as $T$-$DNA$,into the plant genome. In biotechnology,the Ti plasmid of $Agrobacterium$ $tumefaciens$ is modified to serve as a cloning vector for the delivery of genes of interest into plants.

Column-$I$	Column-$II$
$(a)$ Ligase	$(i)$ It removes nucleotides from $DNA$ ends.
$(b)$ Endonuclease	$(ii)$ Connects parts of $DNA$.
$(c)$ Exonuclease	$(iii)$ Removes phosphates from $DNA$.
$(d)$ $DNA$ Polymerase	$(iv)$ It produces sticky ends in $DNA$.
	$(v)$ Useful for repeated amplification.
