$DNA$ strands are antiparallel because of the presence of
$H$ -bonds
Peptide bonds
Disulfied bonds
Phosphate-diester bonds
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.
Histones are rich in the basic amino acid ...............and........
Adenine is $30\%$ then what would be the $\%$ of guanine
In a typical nucleosome if Adenine are $10$ then how many Guanine are present ?
