1 Mutation Notes

2 Chromosomal Mutations
Changes in the genetic material. Gene Mutations Changes in one or a few nucleotides. Chromosomal Mutations Changes in whole chromosomes.

3 Point Mutations or Substitutions
Gene Mutations Changes in one or more nucleotides Point Mutations or Substitutions Changes that occur at a single point in the DNA sequence. Frameshift Mutations Changes that shift the reading of the frame.

4 Point Mutations Silent Nonsense Missense
Changes at a single point in the DNA Sequence Silent Mutation that causes no change in the amino acid sequence. Nonsense A mutation that results in a premature stop codon. Missense Result in a change in the amino acid sequence.

5 Mutation Video Frameshift mutation Deletion of a Nucleotide
Causes all amino acids to change beyond the point of insertion/deletion Insertion of a Nucleotide Mutation Video
