There is a theoretical protein called largeX that helps to stimulate growth of the body during adolescence. The promoter on the lrgX gene that codes for it normally can have a protein bind to it that promotes transcription called Largene. Largene, bound to the promoter, can receive yet another signal in the form of largeXase—a protein that changes the conformation of largene so that it can no longer bind to the promoter. Predict what would happen to an individual if he or she began expressing a lower level of largene than normal at puberty. The individual would show

a. degradation of lrgX

b. a smaller phenotype than others

c. an abnormally large height

d. an alternative form of largeX

The correct answer is option b. "a smaller phenotype than others".

Explanation:

Largene acts as a transcription factor that promotes the transcription of lrgX, a gene that is translated into a protein that stimulate growth of the body during adolescence. In this scenario, if an individual expresses a lower level of largene than normal at puberty, the individual will have a smaller phenotype than others. A lower level of largene will result in a lower level of transcription of lrgX, affecting the stimulation of the body's growth.

b) a smaller phenotype than others

Explanation:

In the above scenario, Largene is a protein which is a transcription factor bind to promoter to increase the expression of lrgX gene and ultimately translateed the largeX protein which will help in the growth of body during adolescence.

So, if there will be low level of expression of largene than normal, it will not bind to promoter effectively or the largeXase can change the conformation of largene which will directly affect the promoter region because promoter will not activate more due to lower level of largene and at the result there will be very low level of expression of lrgX gene. Then largeX protein will be low and it will definitely affect the growth of body during puberty. The growth will be slower than other normal persons.

So, smaller phenotype will be observed than other normal ones.

i think it’s c but i might be wrong. if i am let me know! have a good rest of your day as well!

above statement is not a true statement about the open ocean because the open ocean has low levels of nutrients. most of the photosynthetic activity on earth occurs in the open ocean within the photic zone. organisms in the deep ocean are exposed to frigid temperatures and total darkness but it does not begin at the low-tide mark.
