Answer:
Nucleotide bases.
Explanation:
Unique sequences of bases makes up a nucleotide. These nucleotide sequencing are used by DNA as a genetic code of information that determines type of cells, proteins and the whole organismal structure.
There are four nucleotide bases, Adenine and guanine termed purines are big, cytosine and thymine called pyrimidines are small. A purine pairs with a pyrimidine, such that adenine pairs with thymine and guanine pairs with cytosine. The bases are the same but each DNA uniqueness lies in the sequence of base pairing.
