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.
Point mutations can be subdivided into three types: 1) Nonsense mutations are the ones which code for the same amino acid. 2) Missense mutations occur in the genes which code for different amino acid. 3) Silent mutations do not affect the function of the proteins and code for different or same amino acid.
