WebApr 13, 2024 · A frameshift mutation in a gene refers to the insertion or deletion of nucleotide bases in numbers that are not multiples of three. This is important because a cell reads a gene’s code in groups of three bases … WebA deletion mutation is caused by the removal of one or more nucleotides. A deletion of three bases will typically only affect one or two amino acids, but a deletion of one or two bases disrupts all the codons “downstream” of the mutation and affects the entire remaining reading frame of the gene (a frameshift mutation ).

WebIn a nonsense mutation, a change in the genetic code leads to a STOP codon instead of an amino acid codon. Therefore the rest of the protein isn't formed because the translation process is halted early by the STOP codon. WebOct 4, 2024 · This completely changes the amino acids that would be produced, which in turn changes the structure and function of the resulting protein and can render it useless.
