Question

Assertion (A): Electroporation makes a bacterial cell a competent host to take up DNA.

Reason (R): This technique induces temporary pores in the plasma membrane of the host cell to facilitate entry of foreign DNA.

Options

• Both assertion (A) and reason (R) are true, and reason is the correct explanation of assertion.

• Both assertion (A) and reason (R) are true, but reason is not the correct explanation of assertion.

• Assertion (A) is true but reason (R) is false.

• Both assertion (A) and reason (R) are false.

Answer 1

Both assertion (A) and reason (R) are true, and reason is the correct explanation of assertion.

Explanation:

Electroporation temporarily creates pores in the host-cell membrane. These pores allow foreign DNA to enter and make the cell competent to take it up.
