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
