You are growing bacteria with an inducible operon for the use of lactose as a source of energy. The culture medium has not lactose but at one-time point you add lactose to the medium. Which temporal sequence of events do you expect to see over time?
a) 1. Increase in Beta-Galactosidase mRNA. 2. Increase in Beta-Galactosidase. 3. Increase in lactose consumption.
b) 1. Increase in Beta-Galactosidase. 2. Decrease in Beta-Galactosidase mRNA. 3. Decrease in lactose consumption.
c) 1. Increase in lactose consumption. 2. Increase in Beta-Galactosidase mRNA. 3. Decrease in Beta-Galactosidase
d) 1. Decrease in Beta-Galactosidase mRNA. 2. Increase in lactose consumption. 3. Decrease in Beta-Galactosidase.
e) 1. Decrease in Beta-Galactosidase mRNA. 2. Decrease in Beta-Galactosidase. 3. Decrease in lactose consumption.
Which cellular proceses occur as a consequence of differential control of gene expression in eukaryotic cell?
a) cell differentiation
b) differential translation
c) differential polymerization
d) DNA replication
