Question

Watson and Cricks experiments Which of the following data were available to Watson and Crick when they were trying to determine the structure of DNA? Check all that apply: DNA is composed of 3 basic components: five-carbon sugars, phosphate groups, and 4 different nitrogenous bases. AIl DNA molecules have the same proportions of adenine, guanine, cytosine, and thymine. In DNA, the proportion of adenine always equals that of thymine, and the proportion of guanine always equals that of cytosine: X-ray diffraction patterns indicate that the DNA molecule has the shape of a helix. The DNA molecule is composed of 2 polynucleotide chains that are held together by hydrogen bonds between the nitrogenous bases_ The replication of DNA is semiconservative_ DNA always has an equal proportion of purines and pyrimidines: During DNA replication, synthesis of the leading strand is continuous and synthesis of the lagging strand is discontinuous_ The 2 strands of DNA are antiparallel:
