Which оf the fоllоwing is а common myth аbout аging?
There is аn аnаlоg mоlecule оf allolactose called Isopropyl β-D-1-thiogalactopyranoside (IPTG). IPTG readily enters bacterial cells, and can bind to LacI and release it from the operator, but bacteria cannot metabolize IPTG. Imagine you have two bacterial cultures, one grown on normal media, and the other grown with a strong dose of IPTG, both initially in the absence of lactose. During early growth phases, you add a dose of lactose to each culture while glucose is still abundant. Given what we know about the wild-type lac operon, what is the expected result? [blank1] You repeat the experiment, this time adding a dose of lactose to each culture once their growth has halted because glucose is a limited resource. Given what we know about the wild-type lac operon, what is the expected result? [blank2] In the previous experiment, should you expect both cultures to metabolize lactose at the same rate? [blank3]
