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.

What type of mutation would cause a 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.

Which type of mutation has the least effect?

A point mutation—the change of a single nitrogen base in a DNA sequence—is usually the least harmful type of DNA mutation.

What is the least common type of mutation?

Silent and nonsense mutations can also occur, but these are more specific and, therefore, less common types of substitution mutations. They lead to either a stop codon (nonsense mutation) or a near identical codon to the original being formed.

Which one of the following is least likely to cause mutations in DNA?

Which one of the following is least likely to cause mutations in DNA? light from an incandescent bulb. Which of the following statements about mutations is incorrect? -If a mutation occurs in a germ line cell, the resulting fertilized embryo will carry the mutation in every cell.

Which is a point mutation and not a frameshift mutation?

All the amino acids after the frameshift mutation were affected. 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.

Can nonsense mutation be frameshift?

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.

Is substitution a frameshift mutation?

Frameshift mutations do not include substitutions where a nucleotide replaces another.

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.

Which mutation would be most likely to have the least effect on the functioning of a protein?

Silent mutation: Some mutations that change DNA bases do not have any effect on the sequence of amino acids in the protein. These mutations are called silent mutations and they do not affect the structure or function of the protein because there is no effect on the amino acid sequence.

Which one of these mutations is least likely to affect a protein?

Silent mutations are least likely to affect protein function.

Which mutation would most likely have the least severe consequences?

synonymous (silent) mutation. Which of the mutations would most likely have the least severe consequences? A match between the DNA in a sample and the genomic DNA of a particular individual for a single tandem repeat site is not sufficient to establish identity. However, a mismatch is definitive.

What are the two types of frameshift mutation?

Frameshift mutations occur in two types - insertion mutations and deletion mutations. The overall effect of both is similar - the translational reading frame is "shifted" out of alignment, resulting in a random amino acid sequence.

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.

What are the two primary types of frameshift mutations?

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

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

The correct answer is (e) a deletion of one nucleotide.

What are the 4 types of mutation?

Is deletion a point or frameshift?

A frameshift variant occurs when there is an addition or loss of nucleotides that shifts the grouping and changes the code for all downstream amino acids. The resulting protein is usually nonfunctional. Insertions, deletions, and duplications can all be frameshift variants.

Why is a frameshift missense mutation more likely?

Why is a frameshift missense mutation more likely to have a severe effect on phenotype than a nucleotide-pair substitution missense mutation in the same protein? A substitution missense affects only one codon, but a frameshift missense affects all codons downstream of the frameshift.

What kind of mutation is more likely to result in a nonfunctional protein a frameshift resulting from an insertion or deletion or point mutation?

A frameshift mutation is more likely to result in a nonfunctional protein.

Which mutation would most likely not cause a change in the organism?

If a mutation doesn't cause any change to the resulting protein, what type of mutation do you think this most likely is? Although there are other possibilities, the most likely mutation would be a silent point mutation where a single base is changed, but the changed codon still codes for the same amino acid.

Which mutation is likely to cause more problems a point mutation or a frameshift mutation?

Frameshift mutations have a greater effect tan point mutations because it throws off the reading frame since codons code for different amino acids. If GUA is changed to GUU, will the resulting protein be affected?

Is point mutation same as frameshift?

What is the difference between frameshift mutation and point mutation? In a frameshift mutation, deletion or insertion of one nucleotide leads to change in the reading frame of codons in a gene from that point onwards, whereas in point mutation, there is a change in only one base pair of DNA due to substitution.

Which of these mutations would be least likely to affect the phenotype of the organism?

A. Correct – silent mutations change the genetic code of the DNA, but do not result in changes to the protein function. Therefore, the phenotype of the organism is not affected.
