In an experiment, $DNA$ is treated with a compound which tends to place itself amongst the stacks of nitrogenous base pairs. As a result of this, the distancebetween two consecutive base increases. from $0.34- 0.44\,nm$ calculate the length of $DNA$ double helix $($ which has $2 \times 10^9\,bP)$ in the presence of saturating amount of this compound.
$2 \times 10^{9} \times 0.44 \times 10^{-9} / \mathrm{bp}=0.88 \mathrm{~m}$
The double helix model of Watson and Crick is known as
The length of a helix of $DNA$ is
$DNA$ strand is directly involved in the synthesis of all the following except
The given figure shows the structure of nucleosome with their parts labelled as $A,\, B$ and $C$. Identify $A,\,B$ and $C$
Nucleic acids exhibit secondary structure. Describe through Watson-Crick model.
