  • Question 3
    30 seconds
    Q. which process is shown?
    answer choices
    diffusion

  • Question 4
    60 seconds
    Q. When an extra base is inserted into the DNA sequence of a gene, the protein doesn't work. Which explains why?
    answer choices
    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
