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 the most common type of mutation. A single point mutation, also called a base substitution, occurs when a. single nucleotide is replaced with a different nucleotide. A point mutation results in a base pair substitution after replication and. possibly a mutant protein after transcription and translation.
