Outline the roles of RNA in eukaryotic gene regulation.

Question

Accepted Answer

Hello, everyone and welcome to today's video. So R N A plays a major role in the regulation of gene expression in eukaryotic cells. Which of the following statements regarding the roles of R N A in eukaryotic gene regulation is true. Now, remember from previous videos that R N A is going to be encompassing a large group of molecules that have different roles. So we only not see M R N and R N polymer, but there is many other molecules that are involved in processes inside of the cell. Now let's go over each of our answer choices that we so that we can solve the problem as answer to is A, we have R N A can be used to regulate the stability of M R N A by controlling the rate of M R N A, the gradation. Well as it turns out there is a specific molecule of R N A called R and A and this R N A is is going to be doing just this is going to be controlling and degrading these M R N A molecules. This is a true statement. So we're not going to cancel it out. Then we have B R N A can also be used to regulate the splicing of M R N E, which is the process of removing introns and joining axons together. Now M R N A splicing is going to be done by a larger molecule. However, this larger molecule is going to contain this S N R N P S S and these are smaller R N A molecules that make up the larger molecules. So they are also R N A and they're also going to be performing this process. This is a true statement. So we're not going to cancel it out. Then we have C R N A can also act as a regulatory molecule binding into specific DNA sequences and modulating the expression of genes. So an example of this is going to be R N A polymerase, R N A polymerase is going to bind to DNA sequences and it's going to help express certain genes. This is a true statement as well. And this is just another the R N A molecule. So we're not going to cancel it out since we were not able to cancel out any of our answer choices. The correct answer is going to be D all of the above. I really hope this video helped you and I hope to see you on the next one.
