<span>The information that
determines what the organism will be like is the DNA molecule. It is made up of
nucleotides. These nucleotides are linked chains. The four types of bases found in nucleotides are: adenine,
thymine, guanine, cytosine. The order of the bases determines what instructions are contained on the strand. For example, say a strand shows
ATCTT and say that presents in a person who has blue eyes while other eye
