Base pairing is the specific bonding of complementary nucleotide bases to one another in a nucleic acid. In base pairing, a purine bonds with a pyrimidine; specifically, guanine forms a bond with cytosine, and adenine bonds with either thymine or uracil, depending on the type of nucleic acid involve

Base pairs are held together by hydrogen bonds. Depending on the nucleotides that make up the base pair, there are either two or three hydrogen bonds. Hydrogen bonds are not actually bonds, but significant attraction forces between positively charged hydrogen atoms of one molecule and a negatively c
