Which of the following is an example of a frameshift mutagen?

The correct answer is (e) a deletion of one nucleotide. Frameshift mutation is a category of mutations that includes deletion and insertion of a... See full answer below.

What are some examples of frameshift mutation diseases?

Diseases caused by frameshift mutations in genes include Crohn's disease, cystic fibrosis, and some forms of cancer.

What is frameshift mutation explain with example?

A type of gene mutation in which the addition or deletion of one or more nucleotide(s) causes a shift in the reading frame of the codons in the mRNA, which may lead to the alteration in the amino acid sequence at protein translation is known as frameshit mutation.

What types of mutations are frameshift?

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. A DNA sequence is a chain of many smaller molecules called nucleotides.

Which mutagen causes frameshift mutation?

Proflavin is an acridine dye that intercalates itself between base pairs of the DNA chain thereby causing loss or gain of a single nucleotide. The gene mutation alters the base sequence of the whole genetic frame from the point of mutation called frameshift mutation. So the correct answer is option is B. Proflavin.

Which is a frameshift mutation quizlet?

A frameshift mutation (also called a framing error or a reading frame shift) is a genetic mutation caused by indels (insertions or deletions) of a number of nucleotides in a DNA sequence that is not divisible by three.

Which of the following are true of frameshift mutations?

Which of the following are true of frameshift mutations? They are caused by extra or missing nucleotides in a DNA sequence.

What are two frameshift mutations?

We have identified in exon 7 two frameshift mutations, one caused by a two-nucleotide insertion and the other caused by a one-nucleotide deletion; these mutations–CF1154insTC and CF1213delT, respectively, are predicted to shift the reading frame of the protein and to introduce UAA(ochre) termination codons at residues ...

How do you identify a frameshift mutation?

Frameshift mutations in microsatellites can be identified by extraction of DNA from both normal and tumor tissue (usually paraffin-embedded tissue), amplification of selected microsatellites by PCR, and analysis of fragment size by gel electrophoresis or an automated sequencer (Fig.

How common are frameshift mutations?

A frameshift mutation can drastically change the coding capacity (genetic information) of the message. Small insertions or deletions (those less than 20 base pairs) make up 24% of mutations that manifest in currently recognized genetic disease. Frameshift mutations are found to be more common in repeat regions of DNA.

What is a frameshift mutation give an example quizlet?

1b. What is a frameshift mutation? Give an example. Two kinds of frameshift mutations are insertion and deletion. Insertion is when a nucleotide is added, deletion is where a nucleotide is deleted.

Is CF a frameshift mutation?

We have identified in exon 7 two frameshift mutations, one caused by a two-nucleotide insertion and the other caused by a one-nucleotide deletion; these mutations--CF1154insTC and CF1213delT, respectively, are predicted to shift the reading frame of the protein and to introduce UAA(ochre) termination codons at residues ...

Is Crohn's disease a frameshift mutation?

Here we show, by using the transmission disequilibium test and case-control analysis, that a frameshift mutation caused by a cytosine insertion, 3020insC, which is expected to encode a truncated NOD2 protein, is associated with Crohn's disease.

Is a frameshift mutation a point mutation?

Some scientists recognize another type of mutation, called a frameshift mutation, as a type of point mutation. Frameshift mutations can lead to drastic loss of function and occur through the addition or deletion of one or more DNA bases.

Which mutation is least likely to be a frameshift mutation?

What is the sequence of the transcript? Which of the following mutations is LEAST likely to cause a frame shift? A mutation that removes 6 nucleotides from a sequence.

Which is a point mutation and not a frameshift mutation mutagen?

A frameshift mutation is an insertion or deletion of a nucleotide base that changes the reading frame. A point mutation does not change the frame and only changes one amino acids.

Which of the following mutations would cause a frameshift mutation quizlet?

deletion (one base is removed from the DNA sequence) cause a change in the order of codons that bring about change in the mRNA translation, unlike substitution, these mutations are classified as frameshift mutations.

Why is it called a frameshift mutation?

Thus, if a mutation, for example, an insertion or a deletion of the nucleotide, occurs, this could result in the alteration of the reading frame. It completely changes the amino acid sequence. Such mutations are known as frameshift mutation (also called reading frame mutation, reading frame shift, or framing error).

Is silent a frameshift mutation?

A silent mutation occurs when a mutation does not change the amino acid coded for by that codon. A frameshift mutation is an insertion or deletion that changes the reading frame of the entire protein and can have severe detrimental effects. A radioactive mutation is not a specific classification of mutations.

What type of mutation causes Crohn's?

Mutations in the ATG16L1, IL23R, IRGM, and NOD2 genes appear to increase the risk of developing Crohn's disease. Research suggests these genetic variants affect the presence of bacteria in the digestive system. Changes in this bacteria can harm the ability of intestinal cells to respond to it normally.

What type of gene mutation is cystic fibrosis?

Summary. Cystic fibrosis is caused by mutations in the gene that produces the cystic fibrosis transmembrane conductance regulator (CFTR) protein. In people with CF, mutations in the CFTR gene can disrupt the normal production or functioning of the CFTR protein found in the cells of the lungs and other parts of the body ...

What is Crohn's disease and what does it do to you?

Crohn's disease is a type of inflammatory bowel disease (IBD). It causes inflammation of your digestive tract, which can lead to abdominal pain, severe diarrhea, fatigue, weight loss and malnutrition. Inflammation caused by Crohn's disease can involve different areas of the digestive tract in different people.

Which of the following is an example of a mutagen?

Examples of mutagens include radioactive substances, x-rays, ultraviolet radiation, and certain chemicals.

What are two kinds of frameshift mutations quizlet?

Two kinds of frameshift mutations are insertions and deletions.

Which of the following are types of mutations quizlet?

The two main types of mutations are gene mutations, which can either be point mutations (happening in a single or a few nucleotides) or frameshift mutations (when a nucleotide or nucleotides are inserted or deleted), and chromosomal mutations, which involves changes in the structure or number of the entire chromosome, ...
