Vedclass · Answer

(D) The $Ti$-plasmid (tumor-inducing plasmid) is found in $Agrobacterium$ $tumefaciens$. It is used by the bacterium to transfer its genetic material into the host plant, causing tumor formation. When this plasmid is modified for use as a cloning vector in genetic engineering, the genes responsible for tumor formation (the oncogenes, specifically those encoding for auxin and cytokinin production) are removed. This makes the plasmid 'disarmed', allowing it to carry the desired gene into the plant without causing disease.
