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.
Two types of gene mutations are chromosomal and point mutation.  Chromosomal mutation alters a cell's chromosomes, while point  mutation replaces single-base pair nucleotideâ¦s with other  nucleotides found in RNA or DNA.
