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.
$2 \times 10^{9} \times 0.44 \times 10^{-9} / \mathrm{bp}=0.88 \mathrm{~m}$
In a nucleus, the number of ribonucleoside triphosphates is $10$ times the number of deoxy $x10$ ribonucleoside triphosphates, but only deoxy\ ribonucleotides are added during the $DNA$ replication. Suggest a mechanism.
