Vedclass · Accepted Answer

Agrobacterium tumefaciens - Tumour

Vedclass · Answer

(A) Agrobacterium tumefaciens (updated scientific name: Rhizobium radiobacter) is the causal agent of crown gall disease (the formation of tumours) in over $140$ species of dicots. It is a rod-shaped,Gram-negative soil bacterium.Symptoms are caused by the insertion of a small segment of $DNA$,known as $T-DNA$ (transfer $DNA$),into the plant cell,which is incorporated at a semi-random location into the plant genome.Option $A$ is correct because Agrobacterium tumefaciens naturally transfers $T-DNA$ into plant cells,causing crown gall tumours.Option $B$ is incorrect because Thermus aquaticus is the source of Taq polymerase,not the Bt-gene.Option $C$ is incorrect because $pBR322$ is a cloning vector (plasmid),not an enzyme.Option $D$ is incorrect because restriction endonucleases are known as molecular scissors,while ligase is known as molecular glue.
