The model of DNA structure proposed by Watson & Crick after analysis of Rosalind Franklin's X-ray crystallography data stated that DNA is: Correct Answer-a double stranded helix DNA polymerase requires a template but not a primer to synthesize a new strand of DNA. Correct Answer-False Watson & Crick and Franklin also proposed (and we know now that this is true) that the backbone of the DNA molecule is composed of: Correct Answer-sugar + phosphate Type the letter of the strand that repr...
