Question

What role do the following cellular components play in the storage, expression, or transmission of genetic information: (a) chromatin, (b) nucleolus, (c) ribosome, (d) mitochondrion, (e) centriole, (f) centromere?

Accepted Answer

Welcome back. Let's look at our next question which of the following statements about cell organelles is or are true. Let's look at our answer choices, noting that choice D. Is both A and C. So we've got a possibility of more than one true statement. Choice A says mitochondria has its own ribosomes and genetic material. This is correct. I'm not going to choose it as an answer since there's a possibility of more than one correct answer, but it is true. Mitochondria do have their own D. N. A. And ribosomes along with chloroplasts as well. They can replicate on their own and without a nucleus and make some of their own proteins. Choice B says ribosomes are present in eukaryotic cells only. Well, this is not true. That's not going to be our answer because they're present in both pro carry outs and you carry outs so they are attached to the membrane and in the cytoplasm present in both of those choice. C. Says the central zone controls the cell cycle and serves as the primary organizing center for micro tubules and answer cells in animal cells. Uh And this answer is true. Also that central does serve as the primary organizing center. It organizes the micro tubules specifically in charge of the spindle assembly. And that sort of works as the master control of cell division and replication. So we see both A and C. Are true. So our answer here is going to be choice D. Both A and C. Are true statements about cell organelles that a mitochondria has its own ribosomes. And genetic material. And see the center zone controls the cell cycle and serves as the primary organizing center for micro tubules in animal cells. See you in the next video.
