What are the three ways chromosomes can cause mutations?
point mutation, insertion and deletion
What is the difference between a point mutation and an insertion and deletion?
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.
What type of mutation is a point mutation?
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 :)
Is pku a point shirt or a frameshift mutation?
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.
Will a point mutation cause the cell to make an incomplete polypeptide if the mutation results in a stop codon?
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.

Which is not a frameshift mutation substitution insertion deletion or point mutation?
frameshift- deletion and insertion point mutation- sustitution
Why does a deletion mutation usually cause more defects during protein synthesis than a point mutation?
Deletion mutations can affect the entire base sequence.
Why does deletion mutation usually cause more defects protein synthesis than a point mutation?
A point mutation will change only one particular base of the codon, so it will only cause a change in one of the amino acids that will make up the protein. A deletion mutation will completely remove a base- causing a change in every amino acid that follows the deletion. Here is an example with a sentence, using three letter words (since amino acids are determined from 3 letter codons). THE FAT CAT ATE ONE RAT. A point mutation would change only one letter (like changing the C to a B). The new sentence is only slightly changed: THE FAT BAT ATE ONE RAT. A deletion mutation would remove a letter (like deleting the C). The new sentence will now be completely changed from the deletion on. THE FAT ATA TEO NER AT. See the difference??? Point mutations usually take place during DNA replication. A single point mutation can change the whole DNA sequence.

What are 3 types of 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.

Why does an insertion mutation usually cause defects during protein synthesis than a point 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.
What are two types of mutation?
From another angle: beneficial and detrimental.
Why does an insertion mutation usually cause more defects in protein synthesis than a point 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.
What is never a frameshift mutation?
Substitution is not ever a frame shift mutation. However, insertion, point mutation, and deletion are all examples of a frame shift mutation.
