Other species have different numbers. ... a base pair is missing; WebThe bases have different shapes and pair up together in specific combinations: A pairs with T, and C pairs with G to make base pairs. Put three billion of these base pairs together in the right order, and you have a complete set of human DNA—the human genome. This amounts to a DNA molecule about a metre long. You have two copies of the genome ...

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.
WebThere are chemical cross-links between the two strands in DNA, formed by pairs of bases held together by hydrogen bonds. They always pair up in a particular way, called complementary base pairing: WebDNA uses four kinds of nitrogenous bases: adenine (A), guanine (G) cytosine (C), and thymine (T). RNA nucleotides may also contain adenine, guanine and cytosine bases, but instead of thymine they have another base called uracil (U). Chargaff's rules
