DNA is short of deoxyribonucleic acid,is the molecule that contains the genetic code of organisms.Its is made up of chemical building blocks called nucleoids.To form a strand of DNA. Most DNA is located in the cell nucleus but a small amount of DNA found in the mitochondria. In red blood cells there is no nucleus and no dna however in white blood cells there is a amount of DNA found which is around billions of cells per unit. Approximately 3 billion of base pairs DNA found in which are in 46 chromosomes which carried the information into a ssequences of pieces called genes
DNA is the chemical name for the molecule that carries genetic instructions in all the living things.Its the hereditary material in human and almost all the other organisms. Dna is valnurable it breaks sunlight and water and these are the enzymes which destroy naturally. But after the death the samples survive in a teeth and bones which helps in measuring the DNA to test.
There are three types of forms of DNA like A Form,B form and Z form.
