A microbiologist designs an experiment to transfer a gene from a pathogenic bacterium into a
laboratory strain of Escherichia colit discover whether the gene confers virulence. One method
for transferring the gene into E. coli would be to use a ligase reaction. restriction digestion.

When E. coli in added to a medium with lactose and no glucose, what happens to the repressor
system of the lac operon? 1. The lac repressor is inactivated 2. Transcription of the lac operon
genes into a single mRNA 3. -galactosidase and lac permease are synthesized 4. Lactose is
rapidly metabolized by enzymes 1, 2,3 and 4 2, 3 and 4 1,3 and 4 1,2 and 3
