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.
Define a genetic mutation and state the types of genetic mutations?
A genetic mutation is a change in the DNA sequence that can affect an organism's traits. The types of genetic mutations include point mutations (substitution, insertion, deletion), frameshift mutations, and chromosomal mutations (deletion, duplication, inversion, translocation).

Why does a deletion mutation usually cause more defects during protein synthesis than a point mutation?
Deletion mutations can affect the entire base sequence.
Which is not a frameshift mutation substitution insertion deletion or point mutation?
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.
Why does a deletion mutation usually cause more defects during protein synthesis than 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.

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.
What is never a frameshift mutation?
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.

What type of mutation occurred in the strand of DNA?
A point mutation occurred in the DNA strand. This is a change in a single nucleotide base, such as a substitution, insertion, or deletion.
What are 3 types of mutation?
The three types of mutations are substitution (where one base is replaced with another), insertion (where an extra base is added), and deletion (where a base is removed). These mutations can alter the DNA sequence and potentially change the resulting protein.
