Question

A primitive eukaryote was discovered that displayed a unique nucleic acid as its genetic material. Analysis provided the following information:

A major hyperchromic shift is evident upon heating and monitoring UV absorption at 260 nm.

Accepted Answer

Hey everyone. Let's take a look at this question together. When is the hyper chronic effect seen in D. N. A. Let's recall what we know about what the hyper comic effect is. So when we're talking about the hyper chronic effect or something called a hyper chronic shift, we know that during the unwinding of D. N. A. The viscosity of the D. N. A decreases and also the U. V absorption increases. And this is called the hyper chrome IQ shift. We have the hyper romick shift. And so looking at our answer choices which type of exposure will lead to that unwinding of DNA that eventually causes the viscosity to decrease and UV absorption to increase. Well, looking at answer choice is B. And D. We see a form of radiation which we actually know that exposure to radiation induces D. N. A. Brakes and breaks are not the same as the unwinding of D. N. A. So B and D. Are incorrect. And then looking at A. And C. We can see low versus high temperature which we note that high temperature actually denature the proteins in D. N. A. And that leads to the unwinding of D. N. A. Because of the nature ring. So that means that answer choice C. Is the correct answer. Because exposure to high temperature leads to the unwinding of D. N. A. Which causes the viscosity of D. N. A. To decrease and its UV absorption to increase. Which is known as the hyper chronic shift or that hyper chronic effect that the question is asking us So answer choice C. Is the correct answer. I hope you found this video to be helpful. Thank you and goodbye.
