Gene Mutations

A change in a gene, group of genes or chromosome that results in a change in the proteins

One nucleotide base is changed so only one amino acid

is affected

A point mutation where one nucleotide base replaces an original nucleotide base

A substitution mutation that has no effect

on amino acids sequence

A mutation that results in an amino acid change

A nucleotide base is inserted or deleted shifting the entire DNA sequence. Entire protein will be changed.

A frameshift mutation where a nucleotide base

is removed from the DNA sequence.

A frameshift mutation where a nucleotide base is added

to the DNA sequence

Mutations that involve parts of or all of

a chromosome

A point mutation where DNA adenine (A)

is replaced by thymine (T) resulting in a single amino acid change during translation(affects blood cell

shape and function)
