Genetic Diversity

Missense mutation: a DNA change that results in different amino acids being encoded at a particular position in the resulting protein

Other types of mutatin

Duplication - one or more bases are repeated

Inversion - a sequence of bases is reversed

Translocation - a group of bases is moved from one location to another

Consequence of mutations

• Have no effect if the mutation is silient

• Change the primary structure of a protein by altering one or more amino acid

• Cause a non-functional protein if the mutation affects an important region on like an active site

• Result in the formation of a shorter polypeptide if a stop codon introduced
