Vedclass · Answer

(A) is true because restriction endonucleases cut $DNA$ at specific recognition sequences,acting like molecular scissors.$R$ is true because when the same restriction enzyme is used on both the vector and the foreign $DNA$,they produce complementary sticky ends (overhanging sequences).These complementary sticky ends can form hydrogen bonds with each other,allowing the $DNA$ fragments to join together with the help of $DNA$ ligase.

$A$ - Restriction endonucleases are also called 'molecular scissors'.
$R$ - When fragments generated by restriction endonucleases are mixed,they join together due to their sticky ends.
