WebApr 24, 2024 · One of the most familiar shapes in science is DNA’s double helix structure. First discovered in 1953, this structure uncovered a wealth of information about our … WebThey used Tinkertoy-like models to show that DNA is shaped like a twisted ladder. This shape is called a double helix. Watson and Crick also figured out that DNA is made of chemicals called bases . The "steps" of the DNA ladder are pairs of bases: adenine (A) and thymine (T) or cytosine (C) and guanine (G).

WebJul 29, 2024 · DNA is most often found in the classic double helix shape. This is made up of two strands running in opposite directions. Each strand will have nucleotide bases sticking out of it — those famous letters of A, T, C, and G. The bases from each strand match up in the middle to link together, with A pairing with T and C pairing with G.
