|
Base-Pair Substitution
|
A type of point mutation; the replacement of one nucleotide and its partner in the complementary DNA strand by another pair of nucleotides. |
|
|
Deletion
|
A mutational loss of one or more nucleotide pairs from a gene. |
|
|
Frameshift Mutation
|
A mutation occurring when the number of nucleotides inserted or deleted is not a multiple of three, resulting in the improper grouping of the following nucleotides into codons.
|
|
|
Insertion
|
A mutation involving the addition of one or more nucleotide pairs to a gene.
|
|
|
Missense Mutation
|
The most common type of mutation, a base-pair substitution in which the new codon makes sense in that it still codes for an amino acid.
|
|
|
Mutagen
|
A chemical or physical agent that interacts with DNA and causes a mutation.
|
|
|
Mutation
|
A change in the DNA of a gene, ultimately creating genetic diversity.
|
|
|
Nonsense Mutation
|
A mutation that changes an amino acid codon to one of the three stop codons, resulting in a shorter and usually nonfunctional protein.
|
|
|
Point Mutation
|
A change in a gene at a single nucleotide pair.
