Which type of mutation point or frameshift do you think is most likely to have the greatest impact on the final polypeptide sequence?

Frameshift mutations have a more dramatic effect on the polypeptide than missense or nonsense mutations. Instead of just changing one amino acid, frameshifts cause a change in all the amino acids in the rest of the gene.

Which mutations frameshift or point have the greatest impact on protein synthesis explain?

Answer and Explanation: The type of mutation that is likely to have the greatest effect on a protein is B. Nonsense mutation.

Which mutation has the biggest impact?

The most serious of these mutations will be the insertion of 2 bases. Becasue the genetic code is read in triplets, a 2 base insetion will alter the reading frame of the code causing a frameshift mutation meaning every amino acid after the site of the mutation will be incorrect.

Which type of mutation has the greatest impact and why?

At the short end of the spectrum, indels of one or two base pairs within coding sequences have the greatest effect, because they will inevitably cause a frameshift (only the addition of one or more three-base-pair codons will keep a protein approximately intact).

Which of the following types of mutation would have the most severe effect?

Deletion and insertion may cause what's called a FRAMESHIFT, meaning the reading frame changes. These are typically one of the most serious types of mutations.

Which type of point mutation would have the greatest effect on the organism?

Which type of point mutation would have the greatest affect on the organism? A nonsense point mutation would have a great effect on an organism because it causes the protein to stop early.

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.

Why is frameshift mutation more harmful than point mutation?

Because an insertion or deletion results in a frame-shift that changes the reading of subsequent codons and, therefore, alters the entire amino acid sequence that follows the mutation, insertions and deletions are usually more harmful than a substitution in which only a single amino acid is altered.

Why do frameshift mutations have a greater effect?

Also frameshift mutations have a greater effect than point mutations because it throws off the reading frame since codons code for different amino acids. Another point is that frameshift mutations have a greater effect than point mutations because insertion and deletion are stronger than substitution.

What is a frameshift mutation?

Definition. A frameshift mutation in a gene refers to the insertion or deletion of nucleotide bases in numbers that are not multiples of three. This is important because a cell reads a gene's code in groups of three bases when making a protein.

Is insertion or deletion more harmful?

In case of deletion or insertion of a particular fragment of the gene, deletion could be more harmful than insertion, because the deleted fragment of the gene will never be replaced at exact size and exact position of the disabled gene.

What 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.

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?

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.

Which of the following mutations would you expect to have the greatest effect on a living cell?

C A mutation that deletes one base in the middle of a gene. Which of the following mutations would you expect to have the greatest effect on a living cell? A A mutation that changes a single base in a region of noncoding DNA.

Which type of mutation is most likely to cause a change in a protein's structure and function?

Answer and Explanation: A frameshift mutation is one that will most likely cause a change in the protein's structure and function. This is because frameshift mutations...

What is the difference between frameshift mutation and point mutation?

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 type of mutation -- point or frameshift usually has a greater effect on an organism?

Frameshift mutations have a greater effect tan point mutations because it throws off the reading frame since codons code for different amino acids.

Which mutation is potentially more harmful or causes greater consequence quizlet?

Because germ-line mutations affect the entire organism, they are potentially more harmful (or beneficial), but this is not always the case. Somatic mutations can cause quite harmful effects such as cancer. 8.

What type of results result in frameshift mutation?

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.

Is a point mutation always damaging?

A point mutation occurs in a genome when a single base pair is added, deleted or changed. While most point mutations are benign, they can also have various functional consequences, including changes in gene expression or alterations in encoded proteins.

Are frameshift or nonsense mutations worse?

Frame shift would be the worst as it would change the most. Missense and nonsense change one point along the chain. Which can be detrimental but if it is, it only changes one protein chain.

Which type of mutation is least harmful?

The majority of mutations have neither negative nor positive effects on the organism in which they occur. These mutations are called neutral mutations. Examples include silent point mutations. They are neutral because they do not change the amino acids in the proteins they encode.

Which of the following mutation or change would probably be least likely to impact or affect the biological function of the protein?

Silent mutations are least likely to affect protein function. Missense mutations are often difficult to predict. If the change is to a similar amino acid or in a non-critical amino acid, the mutation protein may continue to function.

Which kind of mutation will likely have the least amount of impact on the function of a protein?

For example if the structure and properties of the substituted amino acid are very similar to the original amino acid the mutation is said to be conservative and will most likely have little effect on the resultant proteins structure / function.

What is the most common point mutation?

The most common type of substitution mutation is the missense mutation, in which the substitution leads to a different codon being formed than the original.
