$I$ and $II$ are true.

Vedclass · Answer

(C) Statement $I$ is true because $DNA$ is a hydrophilic (water-loving) molecule,and cell membranes are composed of a lipid bilayer which is hydrophobic. Therefore,$DNA$ cannot pass through the cell membrane on its own.Statement $II$ is true because,to introduce recombinant $DNA$ into host cells,the bacteria must be made 'competent' so that they can take up the $DNA$ from their surroundings. This is achieved through various methods like chemical treatment (e.g.,$CaCl_2$) or physical methods like heat shock.

$I.$ $DNA$ being a hydrophilic molecule cannot pass through cell membranes.
$II.$ The bacteria should be made competent to accept the $DNA$ molecule.
