Vedclass · Answer

(D) The correct answer is $D$. $EcoRI$ is a restriction endonuclease,not an exonuclease. Restriction endonucleases cut $DNA$ at specific recognition sequences within the molecule,whereas exonucleases remove nucleotides from the ends of the $DNA$ molecule. $Taq$ polymerase is a thermostable enzyme isolated from the bacterium $Thermus$ $aquaticus$,used in $PCR$. Gene gun (biolistics) uses gold or tungsten microparticles coated with $DNA$ to transform plant cells. $Agrobacterium$ $tumefaciens$ is a natural genetic engineer that transfers $T-DNA$ into host plant cells.
