DNA Replication
Universal Genetic Code
Label the phases of mitosis below
Put an ‘X’ on the diagram below
where each interphase checkpoint
occurs. Write what each checkpoint
checks for.
 What process is occurring
to the right if this was a
somatic cell?
 What is the ploidy of the
initial cell and the new
cells?
 How many chromosomes
would it have if it were a
human cell?
What is the diagram on the left showing
above? The right? Label X, A, B, and C. Which
letter on the left is the same as X on the right?
Draw the complementary DNA strand
above this strand.
**Know the order of the cell cycle and what happens during each phase
