An insertion or deletion of a nucleotide base that alters the reading frame is known as a frameshift mutation.
A point mutation only affects one amino acid and does not alter the frame.
The reading frame may or may not move as a result of the insertion or deletion of a nucleotide or combination of nucleotides. The mutation is referred to as a non-frameshift mutation if it does not result in a shift in the reading frame.
The addition or deletion of certain nucleotide base-pairs from the DNA molecule is referred to as an insertion or deletion.
The reading frame may or may not move as a result of the insertion or deletion of a nucleotide or combination of nucleotides. The mutation is referred to as a non-frameshift mutation if it does not result in a shift in the reading frame.
On the other hand, a mutation is known as a frameshift mutation if the reading frame does shift. Where it occurs will determine how it changes.
