Spontaneous mutations are naturally occurring changes in the DNA sequence that arise without any external influence. These mutations often result from intrinsic cellular processes, such as errors during DNA replication, spontaneous chemical changes in nucleotide bases, or structural instability of the DNA molecule. One major source of spontaneous mutations is DNA replication errors, where DNA polymerase incorporates an incorrect nucleotide during the replication process. Although proofreading mechanisms exist, occasional mismatches escape correction, leading to permanent base pair changes in the daughter strand. Tautomeric shifts are another form of spontaneous mutation, where a nucleotide base transiently __________ ____ _________ _________ ________ _____ ____ _______.
