The mutation of oncogenes may cause cancer. In their proto-oncogene form, oncogenes mutate to become a bad gene, thus activating it unnecessarily. In...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer your ...
In many cases, these extra genes offer no benefit and disappear over the generations. But in some cases, extra genes appear to provide an evolutionary advantage. They may mutate until they take on new functions, and gradually spread through an entire species. Round after round of gene duplicati...
Cancer cells haveunstable DNA, which mutates easily and is therefore constantly changing. This is why there are so many mutations found in cancer cells. This “genomic instability” is viewed as a strong suit by scientists who believe in the mutation theory. They think that the tumor cells ke...
What genetic metabolic phase causes gene mutation? How frequently do genetic mutations occur in nucleotide sequences? What kind of mutation occurs when one base is changed to another at a single location in the DNA? Describe the two mechanisms that create genetic varia...
What causes the change in the JAK2 gene isn't known. PV generally isn't inherited—that is, passed from parents to children through genes. However, in some families, the JAK2 gene may have a tendency to mutate. Other, unknown genetic factors also may play a role in causing PV. ...
It happens when the cells in your lungs mutate, or change. The most common cause of these changes is when you breathe in toxic substances. Lung cancer can develop many years after you have inhaled the damaging fumes. A variety of things cause lung cancer. Cigarette smoke. Smoking causes ...
One source of resistance—or at least unease—was the shoving of us humans toward the wings. It was bad enough to say that a person is merely a gene’s way of making more genes. Now humans are to be considered as vehicles for the propagation of memes, too. No one likes to be calle...
The human immunodefiency virus (HIV), which causes Acquired Immunodeficiency Syndrome (AIDS), is a complex disease to control. Anti-HIV drugs target specific characteristics of the virus. As the virus mutates easily, these characteristics can change, and HIV drug resistance can occur. The high ...

The proliferation of variants has prompted concerns that they might make existing vaccines less effective. BecauseCOVID-19vaccines target a specific area of SARS-CoV-2 called thespike protein, mutations to the spike protein gene may lead to viruses that can cause illness even among those who have...
