WHAT IS THE STRUCTURE OF DNA / DNA IS BASED ON IMPORTANCE OF STRUCTURE?
Deoxyribonucleic acid DNA) is a nucleic acid that contains the genetic instructions used in the development and functioning of all known living organisms (with the exception of RNA viruses.The DNA segments that carry this genetic information are called genes, but other DNA sequences have structural purposes, or are involved in regulating the use of this genetic information. Along with RNA and proteins, DNA is one of the three major macromolecules that are essential for all known forms of life.DNA consists of two long polymers of simple units called nucleotides, with backbones made of sugar and phosphate groups joined by ester bonds.
DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA, but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or DNA.The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine
