A frameshift mutation (also called a framing error or a reading frame shift) is a genetic mutation 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 a change in a single base pair in DNA. A change in a single nitrogenous base can change the entire structure of a protein because a change in a single aminâ¦o acid can affect the shape of the protein. A frameshift mutation is a mutation in which a single base is added or deleted from DNA. A single base is lost from a DNA strand which causes this new sequence with the deleted base, to be transcribed into mRNA. Then, the mRNA is out of position by one base. As a result, every codonafter the deleted base is different.
