BIOL 141 Chapter Notes - Chapter 15.1-15.2: Capsid, Dna Replication, Deoxyribonucleotide
Document Summary
Initially, most biologists believed that genes were made of protein, since proteins are so versatile in structure and function. If protein were genetic material, it would have been located within bacterial cell (pellet): because the injected component (dna) leads to the production of new viruses, genes must consist of dna. 15. 2 testing early hypotheses about dna synthesis: watson and crick hypothesized that existing dna strands serve as template for production of new strands, guided by the rules of complementary base pairing. 0 aka parent generation: transfer cells to medium with n-14 and let them divide once. Collect sample (generation 1: let cells divide again in the n-14 medium. Collect sample (generation 2: centrifuge the three samples and compare dna bands, predictions: If model of semiconservative replication (cid:449)ere true : after 2 generations, there would be two bands- one of low-density dna (n-14) and one of intermediate-density dna (hybrid between n-14 and.
