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.
The two types of single gene mutations are point mutation, where a single point in the DNA sequence is affected, and FRAMESHIFT MUTATION, where a single gene or nitrogen base is deleted or added from the mRNA (messenger RNA) sequence causing a shift in the reading frame of the genetic message.he two types of single gene mutations are point mutation, where a single point in the DNA sequence is affected, and FRAMESHIFT MUTATION, where a single gene or nitrogen base is deleted or added from the mRNA (messenger RNA) sequence causing a shift in the reading frame of the genetic message.
