Question
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 distance between two consecutive base increases. from 0.34nm to 0.44nm calculate the length of DNA double helix (which has 2 × 109bp) in the presence of saturating amount of this compound.

Answer

The length of DNA double helix can be calculated by multiplying the distance between two consecutive base pairs with total number of base pairs.
0.44 × 10-9m × 2 × 109bp
= 0.88m
