Question
Which of the following would result in a frame shift mutation?
- Insertions only
- Substitution only
- Deletion only
- Insertions and deletions
Hint:
A frameshift mutation is a genetic mutation caused by indels of a number of nucleotides in a DNA sequence that is not divisible by three. Due to the triplet nature of gene expression by codons, the insertion or deletion can change the reading frame, resulting in a completely different translation from the original.
The correct answer is: Insertions and deletions
- A frameshift mutation is a genetic mutation caused by indels of a number of nucleotides in a DNA sequence that is not divisible by three
- An insertion changes the DNA sequence by adding one or more nucleotides to the gene. As a result, the protein made from the gene may not function properly. A deletion changes the DNA sequence by removing at least one nucleotide in a gene.
