Write a short essay or sketch a diagram that provides an overview of how recombinant DNA techniques help geneticists study genes.

Welcome back. Let's look at our next problem here. It says plants generated by introducing foreign DNA into a plant cell and then regenerating another plant from that cell are called. So the key here is that we've got genetic modification specifically generated with by introducing foreign DNA. So that term we're looking for is choice C transgenic plants. Um Transgenic plants are genetically modified by introducing D N A from a different species. There's a little confusion here because we have choice. B recombination plants and transgenic plants are created through the use of recombinant DNA technology. But recombinant plants don't necessarily have foreign D N A. In them, recombinant plants are just plants that have been genetically modified so that they have an artificially altered genome. But again, doesn't necessarily have DNA from another species. It could be have a gene mutated by the introduction of a gene mutation, could have portions of the gene deleted or the gene completely knocked out. So, alteration to the plant's genome um done on purpose but not necessarily foreign D N A. So that's why choice B is not the correct answer. Let's look at our other answer. Choices here. Choice a foreign plants. Um These would not be genetically modified transgenic plants have foreign DNA, but you wouldn't just call them foreign plants. So that's why choice A is not the correct terminology. And then finally, choice d research plants um would just be any plants used in any sort of research. So they don't necessarily have to have genetic changes. So also not necessarily genetically modified. So that's why that's not our correct answer choice. So again, plants generated by introducing foreign D N A into a plant cell and then regenerating another plant from that cell are called choice c transgenic plants. See you in the next video.
