Vedclass · Answer

(B) The Assertion is correct: The $Ti$ plasmid of $Agrobacterium$ $tumefaciens$ is a natural genetic engineer that transfers $DNA$ into plants. Scientists have modified it into a cloning vector by removing the tumor-inducing genes,making it safe for gene transfer.The Reason is also correct: Retroviruses have the ability to infect cells and integrate their genetic material into the host genome. By disarming them (removing pathogenic genes),they are successfully used as vectors to deliver desired genes into animal cells.Both statements are factually correct,but the Reason does not explain why the $Ti$ plasmid was modified; it describes a separate mechanism for animal cell transformation. Therefore,the Reason is not the correct explanation of the Assertion.
