Hypokinetic movements include: 1  Bradykinesia. 2  Freezing. 3  Rigidity. 4  Postural instability.
1 Missense-the change in nucleotide leads for a different amino acid. 2  This may have little effect, or it may greatly change the resulting protein. 3  Silent-this type of point mutation is the least harmful as there is no noticeable effect on the protein.
There are three types of point mutations: 1. Silent Mutation: causes no change in the activity of the protein; is. usually the result of a substitution occurring in the third location of. the mRNA codon.
