Which of the Following are Considered to Be Frameshift Mutations

Question

Which of the following are considered to be frameshift mutations?
A) insertions only
B) inversions only
C) deletions only
D) both inversion and insertions
E) both deletions and insertions

Accepted Answer

Frameshift mutations are mutations in which the insertion or deletion of nucleotides changes the reading frame of the DNA sequence. Both deletions and insertions can result in frameshift mutations. Inversions, on the other hand, refer to a reversal of the direction of a segment of DNA and do not cause a frameshift mutation.
