WebYour 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). WebSep 10, 2024 · Why do DNA bases pair up? The nucleotides in a base pair are complementary which means their shape allows them to bond together with hydrogen bonds. The A-T pair forms two hydrogen bonds. The C-G pair forms three. The hydrogen bonding between complementary bases holds the two strands of DNA together. WebBase pairs are found in double-stranded DNA and RNA, where the bonds between them connect the two strands, making the double-stranded structures possible.
