  1. Various sugars and phosphates, see the reference.


  2. "Although it may look complicated, the DNA in a cell is really just a pattern made up of four different parts called nucleotides. Imagine a set of blocks that has only four shapes, or an alphabet that has only four letters. DNA is a long string of these blocks or letters. Each nucleotide consists of a sugar (deoxyribose) bound on one side to a phosphate group and bound on the other side to a nitrogenous base.

        *  adenine (A) - a purine

        * cytosine(C) - a pyrimidine

        * guanine (G) - a purine

        * thymine (T) - a pyrimidine"

    Should help a bit
