A frameshift mutation (also called a framing error or a reading frame shift) is a geneticmutation caused by indels (insertions or deletions) of a number of nucleotides in a DNA sequence that is not divisible by three.
A point mutation is affecting only one or very few nucleotides in a gene sequence.
But a frameshift is the most dangerous to a organism.
There are 2 types of frameshift mutations they are deletion and addition
A deletion mutations is when a nucleotide is taking out.
A addition mutation is when a nucleotide is being added.
