mutations canhappen
by errors made during
DNA replication
substitution-bases swapped for another
GCTACC GCAACC
Deletion-bases removed
GCTACC GLACC
Addition-base inserted
GCTACC GCTGACd
Duplication-base repeated

Translocation-sequence moved from one
place to another
(either on same or
different
chromosome)
