Given the state of knowledge at the time of the Avery, MacLeod,and McCarty experiment, why was it difficult for some scientiststo accept that DNA is the carrier of genetic information?
At that time, why did it seem reasonable for the bases to be on the outside of the DNA molecule and what evidence caused Watson and crick to revise this model?
What evidence did Watson and Crick have at their disposal in 1953? What was their approach in arriving at the structure of DNA?
