120s - Q5
When an extra base is inserted into the DNA sequence of a gene, the protein doesn't work. Which explains why?
the inserted base increases rate of protein production
the inserted base causes the protein to be produced incorrectly and not function
the inserted base causes protein production to stop
the inserted base causes the DNA to only replicate
