Impact of mutations on translation into amino acids

WebFrameshift mutations will change the number of nucleotides in a sequence Certain forms of cancer occur because of mutations in DNA sequences that are located in so-called mutational hotspots. These hotspots are locations in the DNA sequence where mutations occur more often than in other places. WebA frameshift changes the grouping of bases into codons, affecting all the amino acids downstream of the mutation. The cell will keep reading until it reaches a stop codon, which may happen earlier or later than in the original sequence. The Universal Genetic Code All living things read genes the same way.
