What is Life? What controls life? Many answers are possible, based on the philosophical, religious, or economic point of view. But at the biological level DNA forms the genetic molecule that controls life. It has a structure called the double helix and all life is based on this structure.

Guide to Deoxyribonucleic Acid

Genetics is the general term for gene structure, which is based on the double helix. This is based on a cellular molecule called deoxyribonucleic acid, also known as DNA. The molecule has two base pairs of molecules adenine which pairs with thymine, and guanine which pairs with cytosine. There is a backbone made up of a sugar phosphate that is composed of three molecules: pentose sugar, a nitrogen base, and a phosphate base. The structure is complex and it controls the genetic basis of the cell. The study of deoxyribonucleic acid is one of the most important chemical, biological, and evolutionary studies known to science. Bright Hub's articles can guide you to an understanding of the nature of this complex molecule and how it affects life.
