Vedclass · Answer

(A) $Agrobacterium 	ext{ } tumefaciens$ is a soil bacterium that naturally infects plants. It contains a large extrachromosomal circular $DNA$ molecule known as the $Ti$-plasmid (Tumor-inducing plasmid). This plasmid carries the $T-DNA$ (Transfer $DNA$) region, which is integrated into the host plant's genome, causing the formation of crown gall tumors. Therefore, the correct answer is $Ti$-plasmid.

What is the large extrachromosomal plasmid found in Agrobacterium tumefaciens that has the ability to induce tumors called?
