State the length of DNA double helix molecule in a typical mammalian cell.

State law of length.

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 0.44 nm.
