X-ray diffraction crystallography pattern of DNA. One of a series of screen images showing X-ray diffraction patterns from a crystal formed from a small section of DNA containing 8 base pairs. Complex computer programs are used to produce from the images an electron density map of the crystal,which can then be used to determine the molecular structure. This information is useful for the precise tailoring of drugs for prospective cancer treatments. The white spots are concentrations of diffracted X-rays,and the diffuse circular pattern is background 'noise' from residual water in the crystal | |
