Question

Choose all of the following factors involved in combinatorial control of gene expression.

a) Regulatory proteins

b) Response elements

c) Histone Proteins

d) RNA polymerase

e) Glycosylation

Accepted Answer

So this question says, choose all of the following factors involved in com combinatorial control of gene expression. So, any factors here, a, b, c, d, or e, which are involved in regulation of gene expression are correct answers. So, there could be more than one correct answer here. So, take a second and see which ones do you think, are involved in regulation of gene expression? Regulatory proteins, response elements, histone proteins, RNA polymerase, and glycosylation. Okay. So, now, let's go through each of these and see if we can figure it out. So, A says regulatory proteins. Well, this one is kind of simple, regulatory proteins are really involved in regulation of gene expression of some kind. So, a is definitely, sort of very simply, a factor. B says response elements. Now, if you remember, response elements are, associated with nuclear receptors and hormones that definitely affect gene expression. So, b is 1. C says, histone proteins. Now, don't get confused by this answer, because this isn't saying histone protein modifications. It's not saying methylation. It's not saying acetylation. It's just saying histone proteins. Now histone proteins by themselves are just proteins attached to DNA and have nothing to do with gene expression. It's the things that are added on to histone proteins that have things to do with gene expression. So c is not, an answer. Now, if it said histone protein methylation, then that would definitely be an answer. D says, RNA polymerase. Well, RNA polymerase, of course, is involved in transcription and gene expression. So, d is definitely an answer. And e says glycosylation, so what do you think? Is glycosylation, really important for, control of gene expression? No. Glycosylation is an entirely different process, so e is definitely not it. So the answers to this question are a, b, and d. So now, lets move on.
