DNA or deoxyribonucleic acid is the molecule in living organisms wherein the genetic code or <em>genes</em> is stored. The structural conformation of DNA in the nucleus of the cells is called <em>chromatin </em><em />and in cell division, chromatin is grouped into a certain number (46, in humans, for instance) called <em>chromosomes.
</em>DNA provides instructions for hereditary such that a part of DNA is transcribed into messenger RNA or mRNA for the genetic code to be transported outside the nucleus. The mRNA is then translated into polypeptides to form proteins that form specific functions in the human body.<em>

This process is known as the canalization. Canalization term is used as the measure of the ability of any given genotype to result in the same phenotype in-spite of the environmental variability.
