Question

Accepted Answer

Hello, everyone. Let's look at our next question, which of the following statements about euchromatin is true. So we'll read through these four answer choices to think about which one is true. But we'll start with just a quick review. When we think about you chromatin, we always think of it as opposed to the other type of chromatin, heterochromatin. So let's just take a moment to recall from our content videos, the difference between them and one good way to remember it is that eu prefix is used to mean something good or perfect. So if you think of euchromatin as the good chromatin, it can help you remember that that's the chromatin where in general genes are transcribed. So the genes that are present and there's many of them in the euchromatin are the ones that in general are transcribed. And that's because the euchromatin is loosely packed. So it can be accessed by R N A polymerase heterochromatin. On the other hand, is tightly packed and condensed and therefore, in general is not transcribed, there are very few genes in heterochromatin and those that are, there are generally not the really key and crucial ones. So with that in mind, let's dive into our answer. Choices. Looking for the true statement. Choice A says U chromatin is the type of chromatin that contains genes involved in cellular processes that are not essential for the survival of the organism. Well, this would be false as we said, euchromatin is the one that is easy for access for transcription machinery. And therefore you would not have non-essential genes mainly in the euchromatin because that's where the main bulk of the genes that are being transcribed are. So choice A is not a true statement. Non-essential for the survival of the organism. Those types of genes would be more in heterochromatin. Instead, choice B says U chromatin is the type of chromatin that is always condensed and tightly packed regardless of the transcription activity of the genes it contains. Well, this is also false as we went over. It is heterochromatin. That is the chromatin that is tightly condensed. So choice B is also not our answer. Choi says E chromatin is the less condensed form of chromatin which allows for the transcription of genes. Well, as we recalled, that is our correct answer that correctly describes the euchromatin. So choice C will be our answer. But we'll just take a look at choice D to be thorough here. Euchromatin appears as a dense, darkly stained region under a microscope and this is also false. The dense packing of heterochromatin uh co causes it to appear as dense and darkly stained when you visualize it under a microscope. So choice D is not correct. So again, which of the following statements about U chromatin is true. Choice C euchromatin is the less condensed form of chromatin which allows for the transcription of genes. See you in the next video.
