Mamoun Ahram PhD 1 Resources This lecture Cooper Chapter 8 Regulation of transcription in prokaryotes The lac operon 3 Metabolism of lactose In the 1950s pioneering experiments were carried out by François Jacob and Jacques Monod who studied regulation of gene transcription in E coli by analyzing the expression of enzymes involved in the metabolism of lactose . Over the past decade an ever growing arsenal of techniques has helped researchers dissect the innermost secrets of the cell and develop new ways to detect and attack disease These techniques also have been used to produce vast amounts of once rare d Facts & .
