Quick Answer: Which Type Of Mutation Is Likely To Have The Greatest Effect On A Protein?

What are the 2 main types of mutations?

Two major categories of mutations are germline mutations and somatic mutations.

Germline mutations occur in gametes.

These mutations are especially significant because they can be transmitted to offspring and every cell in the offspring will have the mutation.

Somatic mutations occur in other cells of the body..

Which type of mutation appears to have the most significant impact on an amino acid sequence?

1. Which type of mutation (insertion, deletion, or substitution) appears to have the most significant impact on an amino acid sequence? Explain your answer. Insertions and Deletions – they cause frameshifts!

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

missense mutationA missense mutation is a mistake in the DNA which results in the wrong amino acid being incorporated into a protein because of change, that single DNA sequence change, results in a different amino acid codon which the ribosome recognizes. Changes in amino acid can be very important in the function of a protein.

What are the 4 types of mutation?

There are three types of DNA Mutations: base substitutions, deletions and insertions.Base Substitutions. Single base substitutions are called point mutations, recall the point mutation Glu —–> Val which causes sickle-cell disease.Deletions. … Insertions.

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

A silent point mutation would be insignificant because nothing changes, not even the amino acid order. 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 type of mutation would likely have the most drastic effect on a protein?

Frameshift mutationsFrameshift mutations change the reading frame of the genetic code and are likely to have a drastic effect on the encoded protein. Many mutations are neutral and have no effects on the organism in which they occur.

What is a silent mutation?

Silent mutations occur when the change of a single DNA nucleotide within a protein-coding portion of a gene does not affect the sequence of amino acids that make up the gene’s protein.

What are 3 causes of mutations?

Mutations arise spontaneously at low frequency owing to the chemical instability of purine and pyrimidine bases and to errors during DNA replication. Natural exposure of an organism to certain environmental factors, such as ultraviolet light and chemical carcinogens (e.g., aflatoxin B1), also can cause mutations.

What is the difference between a nonsense and a silent mutation?

Key Concepts and Summary A point mutation may cause a silent mutation if the mRNA codon codes for the same amino acid, a missense mutation if the mRNA codon codes for a different amino acid, or a nonsense mutation if the mRNA codon becomes a stop codon.

What are effects of mutation?

By changing a gene’s instructions for making a protein, a mutation can cause the protein to malfunction or to be missing entirely. When a mutation alters a protein that plays a critical role in the body, it can disrupt normal development or cause a medical condition.

What type of mutation is least likely to affect the protein?

The correct answer is (c) substitution. A substitution mutation occurs when one nucleotide is exchanged for another in the DNA sequence.

Which point mutation would be most likely?

A base substitution is a type of point mutation which would be most likely to have a catastrophic effect on the function of a protein. Explanation: mutation is defined as the change in the pattern of the nucleotides which is present in a DNA.
