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 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.
