DNA 1. I can draw and label the structure of DNA. 2. I can show how DNA replicates. 3. I can draw, label and name the stages of protein synthesis. DNA stands for deoxyribonucleic acid. DNA is part of our definition of a living organism. DNA is found in all living things. The structure of DNA can be likened to a twisted ladder (twisted molecule- alpha-helix) The rungs of the ladder are made up of “bases” Adenine (A) is a base. Thymine (T) is a base. Cytosine (C) is a base Guanine (G) is a base. | P a g e Gautham – 10/28/09

A always pairs with T in DNA. C also pairs with G in DNA. The amount of A is equal to the amount of T, same for C and G. Therefore, A+C=T+G Hydrogen bonds hold the bases together. The sides of the DNA ladder are made of sugars and phosphate atoms. Bases attached to a sugar; this complex is called a nucleoside. Sugar + phosphate + base = nucleotide.
