((1.14) With bacteriophages to reprogram gene expression of bacteria Brenner, Jacob and Meselson conducted a classical experiment to test competing theories of RNA as intermediary for the information transfer from genes to the protein-by density gradient equilibrium centrifugation and the use of isotopes. Draw the density profiles of RNA synthesized after phage infection (continuous line) expected both on the Messenger Hypothesis (in box a, below) and the One-Ribosome- One-Protein Hypothesis (box b) relative to the profile of "heavy" ribosomes (dashed line). (Recall that after phage infection the media was switched from heavy to light isotopes.) Brenner, Tauoo, Meselsor low low high density density
