What process did watson and crick use to develop their model of dna, and how did it differ from the controlled experiments used by griffith, avery, and hershey and chase?

Watson and Crick already knew DNA's composition, based on the work of other researchers (Franklin). G A H and C manipulated possible components of DNA that would be able to identify DNA's material.

Explanation:

Watson and Crick is known for discovering the chemical compositions of the DNA.In 1953, they found that DNA has the double helical structure along with the stored information of the human gene.Griffith, Avery, and Hershey and Chase did an experiment to find that DNA is transferred through the generations and concluded that instead of protein, DNA carried the human genes.
