What is the evidence that transfer of DNA from the organelles to the nucleus continues to occur?

Question

Accepted Answer

Hey, everyone. Let's take a look at this question together. What are the sources of DNA for the resulting offspring in the nucleated egg approach? Is it answer choice. A two parental DNA sources, a mother and a father answer choice. B, three parental sources of DNA, nuclear DNA from a mother and a father and mitochondrial DNA from another mother. Answer choice. C three parental DNA origins, two from mitochondria and chloroplast and third from nucleus or answer choice. D none of the proceeding. Let's work this problem out together to try to figure out which of the following answer choices is the correct answer. So, to solve this question, let's recall what we've learned about the nucleated egg approach. So what is the nucleated egg approach? Well, we can recall that the nucleated egg approach is the approach where we take the nucleus of the email with a defective mitochondria and that nucleus of the female with the defective mitochondria is and started in and in nucleated egg from a non defective email. And this method produces and offspring with DNA from three different sources which include nuclear E N A from the mother, nuclear DNA from the father, as well as mitochondrial DNA from the donor. And what we mean by the nuclear DNA is the DNA from the nucleus. So we get that nuclear DNA from the mother with the defective mitochondria, nuclear DNA from the father. And then that mitochondrial DNA from the donor, which means that the sources of DNA for the resulting offspring in the nucleated egg approach comes from three parental sources of DNA, which means that answer choice. B three parental sources of DNA, nuclear DNA from a mother and a father and mitochondrial DNA from another mother is the correct answer. Because in this nucleated egg approach method where we take the nucleus of a female who has a defective mitochondria and we insert it in an nucleated egg from a non-effective female. It produces an offspring with DNA from the original mother, from the original father and that mitochondrial DNA from the donor, which is another mother. So answer choice B is the correct answer.
