Genes. A gene is a length of DNA that codes for a specific protein. So, for example, one gene will code for the protein insulin, which is important role in helping your body to control the amount of sugar in your blood. Genes are the basic unit of genetics.

In humans, there are 46 chromosomes, in the form of 23 pairs. Chromosomes are supercoiled and wound around storage proteins called histones so the DNA can be packaged very compactly. Most of DNA appears to be 'junk' - that is, the base sequences don't make any sense.Cells don't seem to use this for much.he nucleus contains chromosomes (23 pairs in human cell) the chromosomes consists of DNA molecules and proteins(histone and nonhistone proteins) the genes are specific sequence of nucleotides (the building unite of DNA) on the DNA.
