The human genome is all one’s genetic material, passed from generation to generation. The genome contains genes, genes made up of a chemical called DNA. The genes are packed in chromosomes neatly, organically and compactly. The chromosomes are located in the nucleus of the cell, with each contains 23 pairs of chromosomes.
DNA is a nucleic acid molecule that carries the genetic information that encodes the growth and development of life forms including the virus. DNA is often considered to be the genetic material at the molecular level involved in determining traits. During reproduction, DNA molecules are duplicated and passed to the next generation. But that is just a primitive concept of genetics. You may do not know that around DNA has countless interesting things.
