WebApr 9, 2024 · A frameshift mutation occurs. This is seen when a number of DNA nucleotides not divisible by three is added or deleted. Remember, the genetic code is a triplet code where three consecutive nucleotides code for a specific amino acid. This causes a reading frame shift and all of the codons and all of the amino acids after that mutation … WebAug 11, 2024 · Why are the frameshift mutations the most harmful? As stated previously, frameshift mutations are more likely to occur in a region of repeat sequence. When DNA mismatch repair does not fix the addition or deletion of bases, these mutations are more likely to be pathogenic. This may be in part because the tumor is not told to stop growing.

WebIn these so-called frameshift mutations, entire proteins are altered as a result of the deletion or insertion. This occurs because nucleotides are read by ribosomes in groups of three, called codons.
