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 are single base changes, that do not affect the reading frame; that is, the mutation only makes a single change in a single codon, and everything else is undisturbed. There are three types of point mutation:1  Silent Mutation.rameshift mutations alter the reading frame of the DNA. They come in two flavors: 1  Insertion: This mutation inserts a base pair (or more) into the DNA, shifting everything to the right (or left, depending on your point of view) by one base pair.
