Blue-white screening is a technique for the identification of___. It relies on the ability ofto cleave lactose. Blue-white tests take advantage of a molecule calledwhich is similar to lactose in that it is cleaved by B-galactosidase. When cleaved, the(same as previous) turns . If uncleaved, meaning a non- function B-gal gene, the X-gal remains. Therefore, abacterial colony means the B-galactosidase gene is not-functional, and therefore therea recombinant gene inserted into the vector. You’ve inserted a gene for pesticide resistance into your vector. To see if it was successful, you decide to conduct a blue-white screening test. But, uh-oh you are out of X-gal! You do notice some green Slime-gal sitting on the shelf and recall that this molecule works similarly to X-gal, but instead of turning blue when cleaved, it turns green when cleaved. You carry out the test, and find that all of your colonies are green! Was your insertion of the pesticide gene successful?

Which of the following describes a negative feedback loop? when the heart rate is too high, the body sends hormones that continually increase the heart rate higher. when a pregnant woman is in labor, the body sends hormones that increase the intensity of contractions, which then increases the secretion of the same hormones. when blood sugar is too low, the body sends hormones that raise blood sugar until it reaches a typical level and hormone secretion slows. when a person is jogging, the body sends hormones that continually decrease the rate of oxygen supply to the legs.
