In a segment of eukaryotic $DNA$,if the purine bases are $40$,then what will be the number of pyrimidine bases?

In a $DNA$ molecule,the antiparallel strands mean that:

$RNA$ does not contain which of the following?

Which of the following is $NOT$ true for the double-helical structure of $DNA$?

Which organism has a $DNA$ consisting of $4.6 \times 10^6 \, bp$?

In an experiment,$DNA$ is treated with a compound that intercalates between the stacks of nitrogenous base pairs. As a result,the distance between two consecutive base pairs increases from $0.34 \, nm$ to $0.44 \, nm$. Calculate the length of the $DNA$ double helix (which has $2 \times 10^9 \, bp$) in the presence of a saturating amount of this compound. (in $m$)
