Across

1. distribute daughter chromosomes to daughter nuclei

3. division of cytoplasm

6. either stops or continues cell cycle, 3 of these occur at after g1, g2, and mitotic stage.

8. body cells

14. after G1 stage, DNA synthesis or replication. one double helix to two double helix.

16. completion of dna replication to onset of mitosis. cell synthesizes proteins that will aid in cell division.

17. after interphase, this includes mitosis and cytokinesis

18. internal signaling proteins

Down

2. two identical chromatids

4. enzymes that bring about apoptosis

5. g1, s and g2

7. programmed cell death

9. an agent that influences the activities of a cell, so that cell cycles stages follow one another in normal flow.

10. the time from when an eukaryotic cell divides and the daughter cell divides

11. stage before dna replication. cell recovers from previous division, grows in size and increases number of organelles.

12. what each double helix is called

13. cells perform normal everyday processes. cells that normally do not do cell cycle stay in this stage. No preparation for cell division

15. nuclear division
