What is one proposed role for lncRNAs?

Question

Accepted Answer

Hello, everyone and welcome to today's video. So which of the following types of R N E can modulate, promote structure and play an important role in epigenetic regulation. So as answer choice A, we have M R and E as answer choice B, we have T R N A as answer choice C, we have R R N E and as answer choice D we have ink R N E. So let's go over each of our answer choices so that we may solve the problem by just going over the functions of each molecule beginning by M R N A. But remember that M R N A is going to be the trend that is created after transcription. So here the transcription process already happened. So gene expression is not really a thing here anymore. It was already expressed. So we're going to cancel this out, then we have T R N A. And in fact, we're going to look at R R N A as well. This R R N A is going to be what makes up the ribosome. Well, T R N A is going to be the molecule that brings amino acids into it. So they're very much present in the translation process. However, they have nothing to do with this chromatin structure. So we're going to cancel both of them out and that leaves us with D which is ink R N A. Now in A are these new class of epigenetic regulators and they in fact, can alter chromatin structure which is going to affect these epigenetics, this gene expression and how do they do it? Well, they do it through methylation and acetyl, which are both things are going to be affecting the rate of gene expression of certain areas of the chromatin. And therefore, answer choice D in A is going to be the correct answer for this question. I really hope this helped you and I hope to see you on the next one.
