Ch. 11 - DNA Replication and Recombination

Chapter 11, Problem 21

While many commonly used antibiotics interfere with protein synthesis or cell wall formation, clorobiocin, one of several antibiotics in the aminocoumarin class, inhibits the activity of bacterial DNA gyrase. Similar drugs have been tested as treatments for human cancer. How might such drugs be effective against bacteria as well as cancer?

Hey everyone. Let's take a look at this question together determine the incorrect statement about D. N. A. Gyrates. So let's recall what we've learned about what D. N. A guy raise is to try to figure out which of the following statements are incorrect. Will help us figure out what is incorrect about DNA. Let's go ahead and make a few points about what we know is correct. So that we can try to better determine which one of the following statements is not true. So some things that we know about D. N. A guy raise is that it is an essential bacterial enzyme. We know it is also a type two topo. I saw Marie and we know it is responsible or introducing negative super coiling into D. N. A. And this process is A. T. P. Dependent. So looking at the following statements, we can actually identify some of the ones that we have already written down. Such as an A. It is a Type two topo summaries which we know is true about D. N. H. I raise. It introduces those negative super coils into D. N. A. Which we also know is true. And that process of introducing the negative super coiling into D. N. A. Is dependent upon a teepee hydraulic sis which we know is also a true statement. So that would mean that answer choices A. B. And C. Are all true statements about DNA chai race. So they cannot be the correct answer which leaves us with answer choice D. The correct answer because we know that it is that essential bacterial enzyme. However it is actually absent in iron carry outs. So that means that answer choice D. Is an incorrect statement about DNA I raise, making it the correct answer to this question. I hope you found this video to be helpful. Thank you and goodbye.

Textbook Question
In 1994, telomerase activity was discovered in human cancer cell lines. Although telomerase is not active in most human adult cells, all cells do contain the genes for telomerase proteins and telomerase RNA. Since inappropriate activation of telomerase may contribute to cancer, why do you think the genes coding for this enzyme have been maintained in the human genome throughout evolution? Are there any types of human body cells where telomerase activation would be advantageous or even necessary? Explain.

Assume a hypothetical organism in which DNA replication is conservative. Design an experiment similar to that of Taylor, Woods, and Hughes that will unequivocally establish this fact. Using the format established in Figure 11.5, draw sister chromatids and illustrate the expected results establishing this mode of replication.
