point mutation, insertion and deletion
A point mutation is when 1 base pair is swapped out for another one... so instead of an A you might find a C... or T... or G. Also an insertion or deletion of a base pair A mutation of a single point :)
PKU (phenylketonuria) is a point mutation, specifically an autosomal recessive genetic disorder caused by a mutation in the PAH gene. This mutation leads to impaired metabolism of the amino acid phenylalanine. It is not a frameshift mutation, which would involve an insertion or deletion of nucleotides, shifting the reading frame of the gene.
Because a point mutation is the replacement of a single base with another base. Thus, if the replacement base codes for the same type amino acid, such as a hydrophobic type amino acid replacing a hydrophobic amino acid, no change to the protein coded for will occur. If a deletion mutation occurs then the code for the protein is disrupted and the protein product is probably going to be useless to the body and may even cause a disease.
Yes, a point mutation will cause the cell to make an incompelete polypeptide chain that is non-functional, if the mutation results in a stop codon. This type of a mutation is also called as the Nonsense Mutation.
Insertion mutations can affect many amino acids in the protein.An insertion mutation usually causes more defects during protein synthesis than point mutation because an insertion mutation will affect many amino acids in the protein.
Insertion mutations can affect many amino acids in the protein.An insertion mutation usually causes more defects during protein synthesis than point mutation because an insertion mutation will affect many amino acids in the protein.

frameshift- deletion and insertion point mutation- sustitution
From another angle: beneficial and detrimental.
Substitution is not ever a frame shift mutation. However, insertion, point mutation, and deletion are all examples of a frame shift mutation.

Three types of gene mutations are substitution, insertion, and deletion. Another gene mutation would be frame shift. All these mutations can cause deformities of the gene.
Frameshift mutations MAY change every amino acid that follows the point of mutation.
