Nuclei from almost any source may be injected into Xenopus oocytes. Studies have shown that these nuclei remain active in transcription and translation. How can such an experimental system be useful in developmental genetic studies?

Hi, everybody. Let's take a look at this practice problem together, identify which of the following attributes of say no rammed itis elegance makes it a model organism for studying the genetic control of development. So Santa wrapped itis elegance or C elegance is a nematode. Now, what does a nematode have that makes it a model organism? What do we know about model organisms in general? We should recall three main things about model organisms. And the first is that it should be a non human species but have similarities to the human genome. The second is the organism should be well studied and the third is that they should have minimal growth and nutritional needs. So it's easy to maintain them within a research lab. So let's review our answer options. We have option A, its genetics are well known. This is true of C elegance. Option B, its genome has been sequenced. This is also true of C elegance and option C adults contain a small number of cells that follow a highly deterministic developmental program. This is also true of C elegance. The simpler developmental program makes it easier to research. That means the correct answer is option D all of the above. Alright, everyone. I hope you found this helpful and I'll see you soon for the next practice problem.
