Document Summary
Inside or outside cell: the answer would determine what the material was that did the. Transforming : hershey and chase results dna (and not protein) was transforming the bacterial cells. Guanine always equaled cytosine (g = c: this finding was called chargaff"s rule . 1940s: franklin & wilkins studied the structure of dna crystals using x- ray diffraction patterns. They deduced several qualities of dna: it is long and thin, it has a uniform diameter of 2 nanometers, it is helical; twisting like a corkscrew and consisting of repeating subunits. The sequence of only four nucleotides can produce many different combinations: a 10-nucleotide sequence can code for more than 1 million different combinations of the four bases. 11. 4 how does dna replication ensure genetic constancy during. Dna replication produces two dna double helices, each with one original strand and one new strand: the fact of complementary base pairing suggests a model for how.
