What are the similarities and differences in the two types of ncRNAs involved in epigenetic control of gene expression?

Video transcript

Hey everyone. Let's take a look at this question together. How do long non coding RNA. S. L. N. C. R. N. A. S differ from typical M. R. N. A. S. So first let's talk about some similarities between the two. Well we know that we have that five end cap And we also have that three n. Poly a. Hello. And that they are sliced now where they differ. Is that the L. N. C. R. N. A. S. Or those long non coding? Those long non coding RNA. S. Lack and extended open reading frame which this codes or the amino acids and that is found in the typical M. RNA. Is but is not found in the long non coding RNA is. And so how they differ is that they lack an extended open reading frame or answer choice D. The correct answer. Because we know that they both have those five end caps. They both have the poly A. Tails and they're both spliced. However, where they differ is that the L. N. C. R. N. A. S. Or the long non coding RNA is lack an extended open reading frame which codes for the amino acids. So answer choice D. Is the correct answer. I hope you found this video to be helpful. Thank you and goodbye.
