Question

Chimeric gene-fusion products can be used for medical or industrial purposes. One idea is to produce biological therapeutics for human medical use in animals from which the products can be easily harvested—in the milk of sheep or cattle, for example. Outline how you would produce human insulin in the milk of sheep.

Accepted Answer

Welcome back. Let's look at our next problem. It says several medical and industrial products are produced via chimeric gene fusion. Which of the following statements is correct. Regarding chimeric gene fusion choice, A chimeric gene fusion involves the insertion of a new gene into an existing organism. Choice B. It involves the merging of two or more genes from different species. Choice C. It is a technique used exclusively for the production of vaccines or choice D. It involves the deletion of a portion of a gene to create a new hybrid gene. Well, we have a clue in the very word chimeric. A chimera was a mythical beast involving different parts of different animals to create one beast. So that can help guide us to our answer. Choice B. Chimeric gene fusion involves the merging of two or more genes from different species. So when you have two genes from different species and you put them together and then go on to use them, you have chimeric gene fusion. So that's the key element of it. When we look at our other answer choices, uh we have choice a saying that it involves the insertion of a new gene into an existing organism. Well, this is not the correct description because the key aspect of it is that you have genes from different species being fused together. So not just the insertion of a new gene into an existing organism. So that's why choice A is not correct choice. C says that it's used exclusively for the production of vaccines. Well, this is not correct. It has many different applications can be used to produce monoclonal antibodies, can be used to produce biofuels, um can be used to produce various enzymes. And even as we see in our question, it says that several medical and industrial products. So it tells us right there that there's more than one kind of thing being produced. So that should be pretty straightforward to eliminate. And then finally choice D that it involves the deletion of a portion of a gene to create a new hybrid gene. Well, this is incorrect. You're not deleting something you're fusing together genes from different species. So again, our answer choice here is that chimeric gene fusion involve the merging of two or more genes from different species. See you in the next video.
