Answer:
The correct answer is "cells which form white colonies on the ampicillin plates".
Explanation:
X-gal staining, also known as blue–white screen, is a common approach to detect colonies that express the gene of interest that has been incorporated into its genome. The basis of this technique is introducing the gene of interest into a vector that interrupts the expression of beta-galactosidase, which means that in a medium with X-gal the cells that were successfully transformed will be white. In this case, the cells that are transformed will also be resistant to ampicillin. Therefore if they growth in a media with both ampicillin and X-gal, a successful clone will form white colonies.
Answer:
increase
Explanation:
The mevalonate pathway is known to generate isopentenyl pyrophosphate and dimethylallyl pyrophosphate, which are used to synthesize diverse compounds including cholesterol and steroid hormones. The levels of mevalonate in human plasma may be used as a measure of cholesterol synthesis. When the cholesterol level is low, it stimulates its endogenous production by the mevalonate pathway. Since it is well known that the vegetarian diet reduces cholesterol, this diet also increases mevalonate levels.
Two major regions of the ocean floor are the continental margin and the deep-ocean basin.
