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).
