Frameshift mutations occur when a nucleotide or nucleotides are inserted or removed from a DNA sequence, resulting in all subequent reading frames (codons) being shifted by an amount not divisible by three (the width of a codon).
These shifted frames will code for different amino acids than before, and will result in the creation of a malformed (and with very few exceptions, unfunctioning) protein.

∙ 14y agoDiseases caused by frameshift mutations result from an alteration normally a loss or addition of one or two nucleotides in the coding sequence (also known as the open reading frame) of a gene, this alteration can lead to an altered amino acid sequence of the gene product (protien) or can lead to a truncation or elongation of the gene product. These alterations causing either an alteration or more normally a cessation of function which in turn leads to the symptoms associated with the disease.

Why do chromosome mutations occur most often during nuclear divisions?
Chromosome mutations occur during nuclear division because when the sequence of nucleotides are being placed substitutions, and frameshifts can occur, causing mutations. Substitution is when one nucleotide replaces another and frameshift mutation is when a nucleotide deletes, causing codons to be incorrectly read.
Name two major types of mutations?
Frameshift mutations and Point mutations. The difference between the two are that point mutations occur at a single point in the DNA sequence and frameshift mutations shift the "reading frame" of the genetic message.
Mutations that occur at random are called?
Mutations that occur at random are called spontaneous mutations.
What mutation can change every amino acid that follows the point of mutation?
Frameshift mutations MAY change every amino acid that follows the point of mutation.
What are three types of chromosomal mutations?
Insertion, Deletion and Frameshift mutation. These are the 3 basic types of mutation, however, there are other types of mutations: substitution, translocation, duplication, inversion, transversion and transition.
What are the types of mutations that can occur?
nonsense mutation, missense mutation, frameshift muation, deletion or addition mutation

What kinds of mutations are there?
point and frameshift
What are the 4 types of mutations that can occur?
Insertion & deletion also known as frameshift mutationsubstitutionduplication mutationtranslocationGlad we could assist.
What are 3 genetic mutations?
substitution and deletion, frameshift, translocation
Two causes of mutation?
Two types of mutations are Point Mutations and the other is Frameshift Mutations. Piont mutations include; deletions, insertions, and substitutions. These mutations casue a slight change in the amino acid usually resulting in a change in one amino acid. The second type, frameshift mutations involve many changes and almost always results in many changes in the codons.
Are point mutations more harmful than frame shift mutations?
The Frameshift mutation affects more codons rather than in a point mutation depending on where it happens.
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.
Mutations that occur at random are called?
Mutations that occur at random are called spontaneous mutations.
Mutations that cause dramatic changes in protein structure are often?
your mom is what causes the answer, Frameshift mutation.
Is substitution mutations or insertion mutations worse?
Insertions generally are more harmful. An insertion causes a "frameshift" to occur, thus changing the entire amino acid sequence of the entire strand. Substitutions only change one base, which can sometimes not mess up the amino acid sequence at all.
