Gene Expression
PowerPoint Lessons (in chronological order):
Gene expression is controlled at 3 major levels, 2 of which we'll talk about in this unit:
Transcription (examples from prokaryotic operons)
Enzyme Regulation (e.g. inhibition, allosteric regulation, cooperativity from the Biochemistry unit)
Chromosome Structure
