DNA & cell cycle review

What happens during the S phase?

• A checkpoint over the connection of the spindle fibers
• The cell grows
• DNA is replicated
• The cell enters the G0 phase

What happens in cytokinesis?

• The cell fully splits into two cells
• The cell digests its extra DNA
• The cell prepares for mitosis
• There are eight important checkpoints there

At the end of the G1 phase, there's a checkpoint. What is this checkpoint probably checking for?

• To see if the cell has grown enough
• To see if the DNA was correctly replicated
• To make sure the cell does not have cancer
• To make sure that the enzymes aren't amalyzed

Which of the following phases is not included in interphase?

• G1
• S
• G2
• M

What stage of the cell cycle follows S phase?

• G1
• G2
• M
• Cytokinesis

After mitosis and cytokineses, one cell becomes...
