Three types of mutagenesis
Mutagenesis is
typically the result of modification of a base in one
strand, so as to alter the correct pattern of base pairing
with the alternate strand. Mutagenic events include (A)
incorporation of a none-base but base-like substance during
DNA replication, (B) chemical alteration of a
base so as to change its base pairint, or (C)
alteration of bases in an oxidizing / reducing cellular
environment.
