Which of the following can cause a frameshift mutation?

Frameshift mutation are caused by the addition or subtraction of nucleotides from the DNA sequence. Because the genetic code is read in triplets, addition or subtraction of 1 or 2 nucleotides causes a shift in the reading frame.

What are two causes of frameshift mutations?

The two causes of frameshift mutations are the insertion and deletion of one or two bases.

What causes a frameshift mutation quizlet?

frameshift mutations occur when there is an addition or deletion of the original sequence. When a base is added or deleted it changes the reading frame of the ribosome thus changing the the protein from that mutation on. The DNA polymerase can proofread each base it adds at the time it adds it during DNA replication.

What is an example of a frameshift mutation?

Frameshift mutations are apparent in severe genetic diseases such as Tay–Sachs disease; they increase susceptibility to certain cancers and classes of familial hypercholesterolaemia; in 1997, a frameshift mutation was linked to resistance to infection by the HIV retrovirus.

What are two types of frameshift mutations?

Two kinds of frameshift mutations are the insertion and deletion of a nucleotide in a sequence.

The different types of mutations | Biomolecules | MCAT | Khan Academy

What is one way that a frameshift mutation can occur?

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.

Which of the following is caused by an insertion mutation?

An insertion mutation affects DNA by inserting one or more nucleotides into the DNA sequence. This changes the genetic code and thus can change the protein made.

How does a frameshift mutation affect the protein quizlet?

FRAMESHIFT MUTATIONS AFFECT EVERY CODON THAT SUCCEEDS THE MUTATION. BECAUSE FRAMESHIFT MUTATIONS AFFECT MULTIPLE CODONS IT IS MUCH MORE LIKELY TO ALTER PROTEIN FUNCTION THAN A POINT MUTATION. What type of a mutation occurs when a gene has two fewer nucleotides in its sequence? THIS REPRESENTS A DELETION MUTATION.

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 is a frameshift mutation and why are they so damaging?

Frameshift mutations are among the most deleterious changes to the coding sequence of a protein. They are extremely likely to lead to large-scale changes to polypeptide length and chemical composition, resulting in a non-functional protein that often disrupts the biochemical processes of a cell.

Which DNA segment deletion would cause a frameshift mutation?

Frameshift mutations are deletions or additions of 1, 2, or 4 nucleotides that change the ribosome reading frame and cause premature termination of translation at a new nonsense or chain termination codon (TAA, TAG, and TGA).

Is point mutation a frameshift mutation?

Point mutation is an alteration of a single nucleotide whereas frameshift mutation is one or more nucleotide changes, altering the open reading frame of a particular gene. Therefore, the main difference between point mutation and frameshift mutation is their effect on the production of a functional protein.

Which of the following describes a frameshift mutation Mcq?

Which of the following describes a frameshift mutation? Explanation: A frameshift mutation indicates that the reading frame of the sequence in altered, resulting in production of different codons downstream of the mutation.

Will a base substitution will lead to a frameshift mutation?

Insertions and deletions are the main reasons for frameshift mutations. Base substation mutation causes changes in the DNA sequence due to the exchange of one base from another. They also produce incorrect proteins at the end if the mutation is not silent.

How did the frameshift change the amino acids quizlet?

Frameshift results from insertion or deletion, it alters the sequence of bases in codons at the mutation and after the mutation. This changes the amino acid sequence and resulting protein. A point mutation could be a silent mutation, maintaining original amino acid sequence and resulting protein.

Which of the following mutations would be most likely to result in a protein that was still functional?

Many missense mutations result in proteins that are still functional, at least to some degree. Sometimes the effects of missense mutations may be only apparent under certain environmental conditions; such missense mutations are called conditional mutations.

What are the three main causes of mutations?

A mutation is a change in the DNA sequence of an organism. Mutations can result from errors in DNA replication during cell division, exposure to mutagens or a viral infection.

What causes mutation?

Mutations are caused by environmental factors known as mutagens. Types of mutagens include radiation, chemicals, and infectious agents. Mutations may be spontaneous in nature.

What are some examples of things that cause mutations?

Mutations result either from accidents during the normal chemical transactions of DNA, often during replication, or from exposure to high-energy electromagnetic radiation (e.g., ultraviolet light or X-rays) or particle radiation or to highly reactive chemicals in the environment.

What causes mutation Mcq?

Explanation: All the types of errors during DNA replication and damages caused by exposure to radiation or carcinogens leads to mutation.

What occurrence of frameshift mutations are the results?

Frameshift mutations are the result of insertions or deletions that alter the reading frame of the triplet codons, thereby altering translation and altering the structure and function of the protein product.

What is frameshift mutation How does it affect function of a protein?

A frameshift mutation is produced either by insertion or deletion of one or more new bases. Because the reading frame begins at the start site, any mRNA produced from a mutated DNA sequence will be read out of frame after the point of the insertion or deletion, yielding a nonsense protein.

What is a frameshift mutation easy definition?

(FRAYM-shift myoo-TAY-shun) An insertion or deletion involving a number of base pairs that is not a multiple of three, which consequently disrupts the triplet reading frame of a DNA sequence.

Which type of mutation a frameshift or a point mutation has more effect on the organism?

Frameshift mutations are usually some of the most harmful kinds of genetic mutations. In contrast to substitution or point mutations, which only affect one amino acid in the protein chain, frameshift mutations affect all the amino acids downstream of their location.

Which of the following Cannot cause mutations *?

Which of the following cannot induce mutations? Explanation: The agents which cause mutation are called mutagens. Some of the mutagens are X-rays, Gamma rays, Bromine, UV radiation, etc. Chlorine is not a mutagen.
