Crick and Watson were great scientist- good at working together
Very adventurous- prepared to try anything
Didn't work alone- had a team that increased skills and knowledge
Best equipment- microscopes, x ray photography and latest knowledge such as
biochemistry
Built on discoveries that had taken place before
HUGE sums of money were needed to pay for all the work with expensive equipment-
most came from the government and other from industries
WHAT COULD UNDERSTANDING DNA LEAD TO?
Genetic engineering new varieties of plants and animals i.e drought resistant crops
Customised drugs- create drugs for a specific person taking into account their genetic
