Document Summary
Dna-deoxyribonucleic acid (nucleotide) is unique to each person and is specifically designed to control the genetic traits of our cells. James watson and francis crick discovered the structure of dna. Dna is constructed as a very large molecule made by linking a series of repeating units called nucleotides (four bases attached to a sugar phosphate group) There are four bases in dna: adenine, guanine, cytosine, thymine. Each of us has 3 billion base pairs. The sugar molecule in dna is called deoxyribos. Structurally the only way that the bases on each strand could be properly aligned with each other in a double helix configuration was to place at (adenine bonds with. Thymine) and gc (guanine bonds with cytosine) - the concept of base pairing. Dna is involved in production of proteins and dna replication. The order in which the base pairs are arranged defines the role and function of a.
