Document Summary
Controversies in genetic engineering: discovering the structure of dna: the double helix. Wwii story tells us much about problems women face in world of science; how credit is awarded. Major players working on dna structure: linus pauling (usa), rosalind. Franklin (1920-58) and maurice wilkins (university of london) Franklin: analyzed dna using x-ray crystallography; produced a number of very good photos of b form of dna but because there were many images in the photo, did not immediately see the dna structure. Franklin had difficult time working with wilkins; treated her more like a technician than real scientist. Franklin also excluded from many formal and informal scientific networks around same time, francis crick and james watson also working on dna. Crick was physicist who was working on phd in biophysics at cambridge; Watson was phage geneticist neglected own studies to work on structure of dna; wanted to create model that would correlate with a) data found from x-ray diffraction; b) the.
