In addition to autophagy, intermittent fastingenhances DNA repair mechanisms. During periods of fasting, cellsentera state that promotes the repair of DNA damage, which is essential for preventing mutations that can lead to cancer and other age-related diseases. ...
Evolution happens overtime when a species changes or give rise to new and advanced species after many generations. This occurs when the various traits required for survival are accumulated and passed on in every generation in a species over a period of million years. Evolu...
If we could decipher the cis-regulatory code, it would unlock an enormous amount of regulatory information and would allow us to locate cis-regulatory mutations and predict their effect on the organism. The cis-regulatory code has been a long-standing problem and the focus of much research. ...
Lederberg's experiment concluded that mutations occur randomly. He used a non-resistant antibiotic strain of bacteria that was exposed to a particular...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question O...
They aren't quite as penetrating as gamma rays, and just a few millimeters of lead can stop them. That's why you wear a "lead apron" when receiving medical X-rays. Overexposure to ionizing radiation can cause mutations in your genes, which causes birth defects, a raised risk of cancer,...
One intriguing possibility for testing this model’s validity would be an empirical study, provided that the value of some adaptive trait can be measured. In the case of the spotted hyena such a trait may refer to hunting success or physical capabilities. It is well established that adult fema...
However, if the changed amino acid is in a crucial part of the protein, then the protein may be defective and not work as well or at all; this type of change can lead to disease. Other types of mutations in DNA can occur when small segments of DNA break off the chromosome. These ...
The lack of recombination leads to accumulation of repetitive DNA, which can lead to a short-term increase in the size of the Y or W, but which typically results in large-scale deletions, a large reduction in physical size of the sex-limited chromosome, and highly heteromorphic sex ...
Adaptations help organisms, as they serve organisms' survival. Through the study of organism morphology (i.e. form with respect to function), one can... Learn more about this topic: Environmental Adaption & Changes Overview from Chapter 21/ Lesson 9 ...
Why might a tumor with mutations in p53 be resistant to radiation therapy? What 2 ways are radioactive tracers used in organisms? What types of environmental problems can result from ionizing and non-ionizing radiation? How does ultraviolet radiation in sunlight affect the epidermis? (briefly both...
