Question

In this chapter, we focused on how gene mutations arise and how cells repair DNA damage. At the same time, we found opportunities to consider the methods and reasoning by which much of this information was acquired. From the explanations given in the chapter,

How do we know that certain chemicals and wavelengths of radiation induce mutations in DNA?

Accepted Answer

Hey everyone. Let's take a look at this question Together. The Chernobyl accident triggered the release of radioactive iodine iodine 1 31 into the environment. This radioactive contaminant caused an increased risk of cancer and other health related problems among the exposed population. Which of the following is considered one of the main consequences of radioactive iodine exposure. So let's recall what we know about iodine. Specifically iodine 1 31 in order to figure out which of the following is one of the main consequences of the radioactive iodine exposure. So we know that iodine is absorbed as well as stored in the thyroid. And this is important because that build up Of that iodine 1 31. Um It's firsts of radiation which causes D. N. A. Damage and this D. N. A. Damage leads to so growth as well as cell division regulation impairment meaning that the body is not able to regulate the growth of cells and the division of cells which is an issue because this leads to uncontrollable growth of thyroid tissue. And so this leads two Bayreuth cancer. So just to recap, we know that iodine is absorbed and stored in the thyroid. And when we have that build up of that iodine 1 31 it emits bursts of radiation which causes DNA damage and the damage to the D. N. A. Leads to cell growth and division regulation impairment meaning that the body has uncontrollable growth of thyroid tissue which leads to thyroid cancer because that cell growth and division regulation impairment occurs in the thyroid tissues. So this leads to thyroid cancer. So answer. choice B is the correct answer. I hope you found this video to be helpful. Thank you and goodbye.
