WebRedirecting WebThe presence of the X shape in the diffraction pattern indicated to Franklin that DNA strands were helical. Each dash of the X shape marks the repetition of atoms, or atomic repeats, in DNA. Therefore, based on the distances between the dashes, Franklin determined the distance between nucleotides, the smallest repeating units in DNA.

WebA scientist named Rosalind Franklin shot X-rays at blobs of DNA. She took a picture of the pattern the X-rays made. When two other scientists named James Watson and Francis Crick looked at her picture, it gave them an idea. They used Tinkertoy-like models to show that DNA is shaped like a twisted ladder. This shape is called a double helix. WebDNA is a long polymer made from repeating units called nucleotides. The structure of DNA is dynamic along its length, being capable of coiling into tight loops and other shapes. In all species it is composed of two helical chains, bound to each other by hydrogen bonds.Both chains are coiled around the same axis, and have the same pitch of 34 ångströms (3.4 nm).
