DNA

We learned about DNA structure in class. DNA is made up with nucleotides, which are made up by a phosphate, a sugar and a nitrogen base. The tie between the phosphate and the sugar is a phosphodiester bond, and the bond between the sugar and nitrogen base is a hydrogen bond, including bonds between A-T and C-G. A and G are called Adenine and Guanine, which are Purines. T and C are called Thymine and Cytosine, which are Pyrimidines. There are 2 bonds between A and T. 3 bonds between G and C.
