Why might we predict that the organization of eukaryotic genetic material will be more complex than that of viruses or bacteria?

Hi everyone. Let's take a look at this practice problem together. Which of the following assertions regarding the genetic materials of pro carry oats and eukaryotes is incorrect. So identify which assertion is incorrect. Now recall that there's a major difference between pro carry oats and eukaryotes. Prokaryotes are uni cellular and thought to be more primitive. Whereas eukaryotes are multicellular and thought to have evolved from the pro carry oats. So let's take a look at our options. We've got a The genetic material and pro carry oats is not enclosed in the nuclear membrane. This is true. This is not our correct answer. The nuclear membrane is found in eukaryotic only since pro carry outs are more primitive, they lack a nucleus and therefore don't have a nuclear membrane. Next we have be in eukaryotes. There are no ah perons. Each gene is transcribed separately into its M. R. N. A. Recall that an operator john is a set of genes that's transcribed together and produces one single M. A. R. N. A. Operations are in pro carry outs only. And so B is also a true statement. Next we have see in pro carry oats operations or groups of genes that can be transcribed together in a single M. R. N. A. Again, as in B. Yes, operations are functionally related genes that can be transcribed together and it's characteristic of pro carry oats. So that checks out true and recall that in new Kerasiotes protein transcription is a lot more complex. And so C. Is also a true statement. So are false statement is D. The D. N. A. Is wrapped around proteins called his stones. In both. Pro carry oats and you carry outs. So pro Cario D N. A is typically comprised of just one chromosome, whereas in New Karros it's typically more than one chromosome. So you Kerasiotes have a lot larger amount of D. N. A. So it needs to be packed up really small. And this is done using his stones. Pro carry out since they have a smaller amount can get away with just super coiling the D. N. A. Into a small space. And so D. Is the false statement and is the right answer. Alright, everyone. I hope you found this helpful and I'll see you soon for the next practice problem.
