WebCells have a variety of mechanisms to prevent mutations, or permanent changes in DNA sequence. During DNA synthesis, most DNA polymerases "check their work," fixing the majority of mispaired bases in a process called proofreading. Immediately after DNA synthesis, any remaining mispaired bases can be detected and replaced in a process … WebJun 7, 2024 · Mutation rates in humans have been estimated to be on the order of 10− 4 to 10− 6 per gene per generation.
