WebSep 10, 2024 · The Four Bases DNA has four nucleobases: adenine, thymine, guanine, and cytosine. The nucleobases in a DNA strand have preferred partners to form hydrogen bonds with. Cytosine pairs with guanine, and adenine pairs with thymine. These are the base pairing rules that allow DNA replication and protein synthesis to happen. WebI can think of one consequence: In DNA replication, you could get two completely different strands of DNA than what you started with. So, as your cells divide, they would have a different DNA.

Your DNA structure is made up of four base pairs: adenine (A), cytosine (C), thymine (T), and guanine (G). The bases form pairs (base pairs); A with T and C with G. The base pairs connect with a sugar molecule and a phosphate molecule (making a nucleotide) that form a spiral staircase (double helix).
