Answers
1
What must occur BEFORE mitosis takes place?

4
Which of these is NOT part of the cell theory?

7
What is the function of an enzyme
To lower the activation energy

8
Why would it be important for the cell to recognize damaged DNA before Mitosis takes place?
So healthy daughter cells can be produced
So the DNA doesn't have to replicate again
So chromosomes can align during metaphase
