Give descriptions for the following terms: chromosome territory

Accepted Answer

Hi, everyone. Welcome back. Here's our next question. Which of the following statements is incorrect regarding chromosome territory. Well, let's work our way through these answer choices and evaluate them choice. A says chromosome territory refers to the three dimensional region of the nucleus occupied by a particular chromosome. Well, this is correct. It's a true statement. Each chromosome has a particular place that it tends to occupy. It's not a random assignment, smaller chromosomes tend to be towards the interior of the nucleus and larger ones towards the periphery. It's also affected by other different properties of each chromosome. And that is the correct definition of chromosome territory. So since that is a correct statement, it is not our answer. We're looking for an incorrect statement. Choice. B says chromosome territories are thought to play a role in regulating gene expression and maintaining genome stability. Well, this is another correct statement. Chromosome territories. The fact that each chromosome has its particular unique and non overlapping spot is important for nuclear organization and is involved in regulating gene expression and maintaining the stability of the genome. So since that's a true statement, also, it's also not our correct answer choi says chromosome territories can change their position and shape within the nucleus in response to cellular processes like cell division and differentiation. And this is true research has shown that although these chromosomes do have these specific unique territories, um those territories can change position and shape during these cellular processes. So also not our answer. So now we're down to choice D which says each chromosome has multiple territories within the nucleus and this one is incorrect. Each chromosome has this unique single territory in general as part of the organization, the nucleus. So choice D is our answer. And again, which of the following statements is incorrect. Regarding chromosome territory, choice D, each chromosome has multiple territories within the nucleus. See you in the next video.
