A substitution mutation occurs when
a base pair is missing from the DNA strand
a base pair is added to the DNA strand
a base pair is replaced with a different base pair
An insertion/additon mutation occurs when
a base pair is missing from the DNA strand
a base pair is added to the DNA strand
a base pair is replaced with a different base pair
A deletion mutation occurs when
a base pair is missing from the DNA strand
a base pair is added to the DNA strand
a base pair is replaced with a different base pair

Substitution
Deletion
Insertion
Frameshift
A frameshift mutation where a nucleotide base is added
to the DNA sequence
Insertion Mutation
Deletion Mutation
Substitution Mutation
Chromosomal Mutation
One nucleotide base is changed so only one amino acid
is affected
