In the past, science has been dominated by men, and sometimes even when women were involved their efforts were not properly recognised. Thankfully, modern society is very different, and female scientists regularly make important scientific discoveries and win Nobel prizes for science. Follow the links below and on your WebQuest research sheet describe the work done in the discovery of DNA by the scientists Rosalind Franklin, Francis Crick, James Watson and Maurice Wilkins.
