Vedclass · Answer

(B) In $r-DNA$ technology,various methods are used to introduce recombinant $DNA$ into host cells. $1$. Transformation: The process by which a cell takes up naked $DNA$ from the environment. $2$. Electroporation: $A$ technique that uses electrical pulses to create temporary pores in the cell membrane to allow $DNA$ entry. $3$. Transduction: The process by which foreign $DNA$ is introduced into a cell by a virus or viral vector. $4$. Conjugation is a natural process of genetic transfer between bacteria through direct cell-to-cell contact,which is not a standard laboratory technique used for introducing engineered $r-DNA$ into a host cell in the context of $r-DNA$ technology protocols. Therefore,the correct answer is $B$.

Which of the following techniques is $NOT$ used for introducing $DNA$ into a host cell in $r-DNA$ technology?
