The meselson-stahl experiments and this paper are considered important, groundbreaking studies in molecular biology. some of the clarity of the centrifugation results was due to the fact that the dna was fragmented during handling (although the experimenters did not know it at the time.) when dna breaks into fragments, the sugar-phosphate backbone is broken forming many short double helices. why did the fragmented dna still show the same pattern of nitrogen density banding?
