Mutations

What is a genetic mutation?

• A genetic mutation is a random occurrence that has no effect on the DNA sequence that makes up a gene.

• A genetic mutation is a reversible alteration in the DNA sequence that makes up a gene.

• A genetic mutation is a permanent alteration in the DNA sequence that makes up a gene.

• A genetic mutation is a temporary change in the DNA sequence that makes up a gene.

What is a point mutation?

• A point mutation is a change in the structure of a protein.

• A point mutation is a change in multiple nucleotide bases in DNA or RNA.

• A point mutation is a change in the number of chromosomes in a cell.

• A point mutation is a change in a single nucleotide base in DNA or RNA.

What is an insertion mutation?

• An insertion mutation is a type of genetic mutation where a nucleotide or a sequence of nucleotides is removed from the DNA sequence.

• An insertion mutation is a type of genetic mutation where the DNA sequence remains unchanged.

• An insertion mutation is a type of genetic mutation where the DNA sequence is completely replaced by a new sequence.

• An insertion mutation is a type of genetic mutation where an extra nucleotide or a sequence of nucleotides is added to the DNA sequence.

What is a deletion mutation?

• A deletion mutation is a type of genetic mutation where a segment of DNA is duplicated within a gene or chromosome.

• A deletion mutation is a type of genetic mutation where a segment of DNA is inserted into a gene or chromosome.

• A deletion mutation is a type of genetic mutation where a segment of DNA is rearranged within a gene or chromosome.

• A deletion mutation is a type of genetic mutation where a segment of DNA is lost or deleted from a gene or chromosome.

What is a frameshift mutation?

• A frameshift mutation is a type of genetic mutation where the inversion of nucleotides in a DNA sequence shifts the reading frame of the codons, resulting in a completely different amino acid sequence.

• A frameshift mutation is a type of genetic mutation where the substitution of nucleotides in a DNA sequence shifts the reading frame of the codons, resulting in a completely different amino acid sequence.

• A frameshift mutation is a type of genetic mutation where the addition or deletion of nucleotides in a DNA sequence shifts the reading frame of the codons, resulting in a completely different amino acid sequence.

• A frameshift mutation is a type of genetic mutation where the duplication of nucleotides in a DNA sequence shifts the reading frame of the codons, resulting in a completely different amino acid sequence.

What are the three types of genetic mutations?

• substitutions, insertions, and deletions

• substitutions, duplications, and inversions

• missense mutations, nonsense mutations, and frameshift mutations

• frameshift mutations, translocations, and inversions

What is a substitution mutation?

• A substitution mutation is a type of genetic mutation where multiple nucleotides are replaced by other nucleotides in the DNA sequence.

• A substitution mutation is a type of genetic mutation where one nucleotide is deleted from the DNA sequence.

• A substitution mutation is a type of genetic mutation where one nucleotide is replaced by another nucleotide in the DNA sequence.

• A substitution mutation is a type of genetic mutation where one nucleotide is added to the DNA sequence.

What is a silent mutation?

• A silent mutation is a mutation that leads to the production of a completely different protein.

• A silent mutation is a mutation that does not result in any change in the amino acid sequence of a protein.

• A silent mutation is a mutation that only occurs in non-coding regions of DNA.

• A silent mutation is a mutation that completely changes the amino acid sequence of a protein.

• Monohybrid Trait

• Mutation

Why are insertion and deletion mutations so harmful?

• They change all of the codons from the mutation on down the line, which changes the amino acid sequence

• They insert things that an organism doesn't need.

• They often delete things that organisms need.

• Insertion and deletions are not any more harmful than substitution mutations.
