What is DNA?

DNA is what you say?  It is Deoxyribonucleic acid, or DNA for short, is something that every living creature or being has.  It was discovered and researched by two bright men, Watson and Crick.   It is found in the cell.  Every living organism, big or small has a unique set of DNA.  The only exception to that are identical twins.  Genes are passed down from parents to offspring through sex.  Each parent passes traits to the offspring.  Not every offspring is the same because each one receives different genes and receives different characteristics.  DNA consists of deoxygenated ribose and is double stranded.  It can be found in the nucleus and cytoplasm of the cell.  Its shape is a double helix which consists of Purines and Purmydines.  The Purines are Adenine and Guanine and the Pyrmidines are Thymine and Cytosine.  The Adenine links with the Thymine and the Cytosine bonds with Guanine.  DNA is very complicated and has many uses.
