Adenine is $30\%$ then what would be the $\%$ of guanine
$10\%$
$20\%$
$30\%$
$40\%$
What are the structures called that give an appearance as ‘beadsonstring’ in the chromosomes when viewed under electron microscope?
..............is common for both $DNA$ and $RNA$ but.............is present only in $DNA$
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.
If a double stranded $DNA$ has $20$ per cent of cytosine, calculate the per cent of adenine in the $DNA$.
$DNA$ strands are antiparallel because of the presence of
