what type of mutation causes a shift in the reading frame?\nnondisjunction\nframeshift
Answer
Answer:
frameshift
Brief Explanations:
Frameshift mutations, caused by insertions or deletions of nucleotides not in multiples of three, shift the reading frame. Nondisjunction is related to chromosome - segregation errors, not reading - frame shifts.
