    wait , but i thought when everything after one amino acid got deleted it was a nonsense mutation? can framshift mutations also cause nonsense mutations ?

    • @Cararra
      @Cararra  3 ปีที่แล้ว +3

      nonsense mutations are a different categorization of mutation (nonsense means that a normal codon changed into a stop codon, meaning that the protein got cut short but the reading frame remained the same, frameshift means that the reading frame got shifted, so every amino acid basically gets CHANGED [not necessarily deleted] after the deletion or insertion [a stop codon isnt necessarily formed so the protein might still have same length or get even longer])
