Support your argument with mathematical calculations step by

The length of DNA in each one of our cells is roughly 2 meters. Compared to the nucleus of your cells is about 10 microns in diameter. How can DNA fit in your nucleus? Give quantitative argument.

Solution

The DNA is roughly 2 mitres in length but DNA has densely packed structure. The DNA itself negatively super coiled and coiled coil structure. Moreover its densely packed with proteins and makes chromatin. Each chromatin are then packed to form chromosome. Then chromosomes are tightly packed into nucleus. So, as a result although DNA is about 2 mitres on length but the packing structure of the DNA can fit into 10 micron nucleus..
