Posted: (2 days ago) DNA sequencing is essentially another term for “reading the DNA double helix” or determining the sequence of its nucleotides or bases. Nucleotides are comprised of four chemical bases: adenine (A), thymine (T), cytosine (C), and guanine (G). These bases always form the same base pairs within the DNA double helix: A always pairs with T, and C always pairs with G.
