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 :)
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.
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.
Gene mutations that occur at a single point in the DNA sequence are called point mutations. These mutations can involve substitutions of one nucleotide for another (missense mutation), insertion of an extra nucleotide (insertion mutation), or deletion of a nucleotide (deletion mutation). Point mutations can have various effects on the resulting protein, ranging from no impact to severe functional changes.
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.

A point mutation is not a frameshift mutation. Point mutations involve changes in a single nucleotide base, while frameshift mutations involve the insertion or deletion of nucleotide bases, causing a shift in the reading frame of the genetic code.
From another angle: beneficial and detrimental.
A point mutation is never a frameshift mutation because it involves the substitution of a single nucleotide for another rather than the insertion or deletion of nucleotides that would disrupt the reading frame of a gene.
A point mutation occurred in the DNA strand. This is a change in a single nucleotide base, such as a substitution, insertion, or deletion.
No
A frameshift mutation, where an insertion or deletion of nucleotides causes a shift in the reading frame of the genetic code, can change every amino acid that follows the point of mutation. This can have dramatic effects on the resulting protein's structure and function.
