When an extra base is inserted into the DNA sequence of a gene, the protein doesn't work. Which explains why?
the base increases rate of translation
the base causes DNA to be transcribed in opposite direction
the inserted base causes the codons in the sequence to be incorrect for the desired protein
the base signals enzymes to translate DNA rather than RNA
