The double helix model of Watson and Crick is known as
$C-DNA$
$B-DNA$
$Z-DNA$
$D-DNA$
(b)$B-DNA$ is the right handed coiled and normal type of $DNA.$
Assertion : In a $DNA$ molecule, $A-T$ rich parts melt before $G-C$ rich parts.
Reason : In between $A$ and $T$ there are three $H-$ bond, whereas in between $G$ and $C$ there are two $H-$ bonds.
