Which of the Following Can Result in a Frameshift Mutation

A purine is replaced by another purine and a pyrimidine is replaced by another pyrimidine. Therefore frameshift mutations result in abnormal protein products with an incorrect amino acid sequence that can be either longer or shorter than the normal protein.

Point Mutation Versus Frameshift Mutation Point Mutation Mutation Brain Facts

The sequence of three nucleotides of either DNA or RNA is known as a codon.

. Deletion causing a frameshift. Which type of mutation results in a frameshift mutation. Check all that apply.

The gene expression is performed by codons either by insertion or deletion of a base which can change the reading frame of sequencehence the frameshift mutation occurs. Frameshift mutations have a more dramatic effect on the polypeptide. A frameshift mutation is anything that puts the regular order of 3 nucleotides a codon out of its norm.

Our results showed that a germline mutation of STK11 gene can be found not only in probands fulfilling the PJS diagnostic criteria but also in some sporadic cases not complying with the criteria. GCA ATG CAC mRNA. Mechanism of Frameshift Mutation.

Which of the following can result in frameshift mutations. A base pair is added to the DNA within a gene which causes a reading frame shift. Increase genetic variations.

An abrupt halt to the translation process results in non-usable protein which has ramifications for the physiological systems involved. This occurs in the gene - not outside of the coding sequence. Deletion of the DNA segment occurs in anaphase movement or during reorganizing of the nuclei or digestion by nucleases.

The mechanism of frameshift mutation depends on the cause of the mutation. Either an insertion or a deletion of a base a base insertion only a base deletion only deletion of three consecutive bases a base substitution only. DInsertion or deletion of nucleotides that results in a premature stop codon The answer is C because a frameshift mutation indicates that the reading frame of the sequence in altered resulting in production of different codons.

A frameshift mutation is a genetic mutation caused by a deletion or insertion in a DNA sequence that shifts the way the sequence is read. But the following are some of the possible mechanisms of frameshift mutation. Examples of genetic diseases that can be caused by frameshift mutations include Tay-Sachs Disease Cystic Fibrosis Crohns Charcot-Marie-Tooth Disease Hereditary Polyneuropathy and.

Along with substitutions mutations can also be caused by insertions deletions or duplications of DNA sequences. Taking out the first G in the original DNA above results in. A base pair is lost within the DNA of a gene which causes a reading frame shift.

How did the frameshift change the. If these things happen then you get a frameshift. What can result from a mutation.

Change in DNA sequence results in. A protein with a changed coding sequence may be unusable or a totally different protein. Thus this results in a completely different translation product.

Sometimes gene variants also known as mutations prevent one or more proteins from working properly. The engaging quiz is interactive and it can give you instant results. Either an insertion or a deletion of a base.

The following quiz will help you master the effects of frameshift mutations. Deletes a nucleotide in the base sequence. A frameshift mutation is a particular type of mutation that involves either insertion or deletion of extra bases of DNA.

Frameshift mutations can lead to the following outcomes. Which of the following types of mutations could result in a frameshift mutation. CAA TGC AC mRNA.

You dont show the picture but I can give you an overview. Moreover we observed a new case of aggressive gastric cancer in a young patient with a frameshift mutation of STK11 gene. An insertion or deletion can result in a frameshift mutation.

On the other hand when some proteins become dysfunctional they could have a protective effect as seen in the resistance to HIV in people with a chemokine receptor gene CCR5 containing a frameshift mutation. Which of the following would result in a frameshift mutation. The number of bases that are either added or subtracted cant be divisible by three.

Adding or deleting nucleotides which affects every amino acid following the mutation. Mutations something outside the body. Which of the following can result in frameshift mutations.

Which of the following can result in frameshift mutations-alkylating agent-tautomeric shift -base analog-acridine dye -deamination. To demonstrate this complete the following. And thats important because the cell reads a gene in groups of three bases.

Learn vocabulary terms and more with. As a result a variety of metabolic processes may be disrupted. Loss of a single basepair perhaps the A in bold.

Start studying Frameshift Mutation. So the correct answer is Either an insertion or a deletion of a base. Frameshift mutation textbfframeshift mutation frameshift mutation if there is a change in the DNA nucleotide sequence that is not divisible by three which affects the overall reading of codons.

The sequence of the DNA remains the same since the change involves proteins. Now whats important here is the number three. A frameshift mutation is a genetic mutation caused by a deletion or insertion in a DNA sequence that shifts the way the sequence is read.

Diseases caused by frameshift mutations in genes include Crohns disease cystic fibrosis and some forms of cancer. A frameshift mutation is a mutation caused by an insertion or deletion which causes a shift in the translational reading frame.
