What are the main phases of the cell cycle?
Interphase (G1,S,G2) and M phase
What are the 5 stages of mitosis?
Prophase, Metaphase, Anaphase, Telophase & Cytokinesis
What is the most important checkpoint of the cell cycle?
G1 Checkpoint
What type of signaling occurs when cells are close together?
Paracrine signaling
During which pase is DNA replicated?
The S phase
Which phase do sister chromatids separate?
Anaphase
What is a growth factor?
Hormones released by cells that stimulate cell growth
What type of signaling uses hormones that travel through the bloodstream?
Endocrine signaling

Which type of signaling occurs in an animals nervous system?
Synaptic signaling
What do cyclins bind to in order to advance the cell cycle?
CDKS (cyclin-dependent kinases)
What is the difference of cytokinesis in animals and plants?
Animals - a cleavage furrow appears
Plants - a cell plate is formed
