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.
This type of analysis is also used in the type of DNA testing that is used in crime labs or used to determine paternity. POINT MUTATIONS, often caused by chemicals or malfunction of DNA replication, exchange a single nucleotide for another.oint mutations that occur within the protein coding region of a gene may be classified into three kinds... A. nonsense mutations: code for a stop, which can truncate the protein. B. missense mutations: code for a different amino acid. C. silent mutations: code for the same amino acid.
