Why is biochemical purification of one gene away from the other genes in a cell more challenging than biochemical purification of one protein away from the other proteins in a cell?

a) A cell has many more genes that it has proteins.

b) DNA is very unstable and is likely to be broken down during the purification process.

c) Proteins are larger molecules than genes.

d) The chemical nature of all genes is very similar; the chemical nature of various proteins can be very different.

d) The chemical nature of all genes is very similar; the chemical nature of various proteins can be very different.

Explanation:

The isolation of proteins requires protein separation techniques and identification which can identify individual proteins because of their distinct differences as well as different charges but in the case of genes, their chemical nature comprising of DNA are the same.
