Watson and Crick used scientific reasoning, their knowledge of biochemistry, and the research of other scientists to make one of the most important scientific claims of their time: DNA is a double helix with strands running in opposite directions. Between these strands, A pairs with T, and C pairs with G.
While trying to determine the structure of DNA, Watson and Crick at one point proposed that like bases are bonded to like bases. For example, thymine would be bonded to thymine, cytosine would be bonded to cytosine, and so on. Explain why this proposed model would not fit based on what was discovered to be true about DNA.
How did Griffiths and Avery discover that DNA was the molecule of heredity? Would we have been able to discover the structure of DNA without this work? Why or why not? Would we have been able to understand or actually try to understand DNA replication without his work? Why or why not?
