Cell differentiation always involves
a. transcription of the myoD gene.
b. the movement of cells.
c. the production of tissue-specific proteins.
d. the selective loss of certain genes from the genome.

Accepted Answer

Welcome back. Our next problem says differential gene expression and different types of cells results in their proliferation, differentiation, apoptosis or migration. Well, differential gene expression in cells is involves activating some jeans while leaving others dormant. And this establishes um different characteristics in different cells because you have some genes turned off and some genes turned on. So when we look at our choices we see A. Is proliferation which just means you know the the multiplication of cells. But here we're talking about um cells becoming different due to genes being expressed in different ways. So proliferation is not what we're looking for. Be differentiation. So differentiation involves cells becoming different from each other as a result of different genes being turned on and off. So Choice B. Is the appropriate answer here, differentiation is the result of this differential gene expression just to be thorough. We keep looking on choices apoptosis that's programmed cell death. So that's not our answer. As it's we're talking about not cell death but just specific genes being activated or silenced. And then Choice D. Is migration meaning the spread of cells to different parts of the body. But we're talking about cells becoming different. Not necessarily about they're moving to different places. So Choice D. Is not as correct as choice be. So our answer again is be differentiation. See you next time
