Detailed explanation-1: -Other mutations can happen on their own during a person’s life. These are called sporadic, spontaneous, or new mutations. They affect only some cells.
Detailed explanation-2: -Spontaneous mutations are “the net result of all that can go wrong with DNA during the life cycle of an organism” (Glickman et al., 1986). Thus, the types and amounts of spontaneous mutations produced are the resultant of all the cellular processes that are mutagenic and those that are antimutagenic.
Detailed explanation-3: -Spontaneous mutations are derived from various sources, including errors made during replication of undamaged template DNA, mutagenic nucleotide substrates, and endogenous DNA lesions.
Detailed explanation-4: -So, the correct answer is ‘Mutation’.
