Why are changes in nucleosome spacing important in changing gene expression?

Video transcript

Everyone. Let's take a look at this question together. Which of the following is a consequence of having nuclear zones that are spaced closely together when we have those nuclear zones that are spaced closely together, it enders transcription factors from binding in the D. N. A. Grant. And because of this transcription will be prevented. And as a result of that gene expression, well not cur. And so consequence of having those nuclear zones spaced closely together, it hinders the transcription factors from binding in the D. N. A. Strand. So transcription will be prevented and gene expression will not occur. So that means that answer Choice B is the correct answer because these transcription factors cannot bind to the DNA strand due to having those nuclear zones spaced closely together. So answer Choice B is the correct answer. I hope you found this video to be helpful. Thank you and goodbye.
