What is a spontaneous mutation, and why are spontaneous mutations rare?

Video transcript

Everyone. Let's take a look at this question Together, identify the incorrect statement about spontaneous mutations. So let's recall what we know about what spontaneous mutations are to try to figure out which of the following statements are incorrect when we know that a spontaneous mutation involves changes in the nuclear tied sequence uh jeans that appear to occur naturally. And so what this means is they are not associated with specific agents. And so that way there's no specific way to tell whether or not a spontaneous mutation will occur. And so looking at our answer choices, Answer choice A says they're caused by the influence of exogenous factors, which we know that spontaneous mutations are not associated with specific agents. So answer choice A has to be an incorrect statement, thus making it the correct answer, which we also know. It is the correct answer because we know that exogenous factors are muted gens which induced those mutations. And so answer choice A. Is an induced mutation and not a spontaneous one. So answer choice A is the incorrect statement. And it is the correct answer. I hope you found this video to be helpful. Thank you and goodbye.
