Cell Cycle and Mitosis

Before cells can divide, what happens to the DNA?

• It is replicated

• It increases in size

• It is divided in half

• It decreases in size

• 50

• 92

The individual strands on the duplicated chromosomes are called

• chromatin

• chromosomes

• chromatids

• centromere

Put the following stages of the cell cycle in order: G2, S, G1, M. 

• G1, S, G2, M
• S, G1, G2, M
• G1, M, G2, S
• M, G1, S, G2

During the "s" phase of the cell cycle, DNA is duplicated. Why is this important?

• Allows for each daughter cell to be genetically DIFFERENT.

• Allows for each daughter cell to be genetically IDENTICAL

• Allows for each daughter cell to have 2X the amount of DNA as the parent cell.

• Allows for each daughter cell to have half the amount of DNA as the parent cell

(d) Telophase

• 
• Chrosomes seperated and unwind back to chromatin. Nuclear envelopes re-form.

• 
• 
• Chromosomes align at the cell's equator, known as the metaphase plate. The spindle fibers fr

• Chromatin condenses and becomes visible as distinct chromosomes. Each chromosome consists of two

• Sister chromatids are pulled apart. Chromatid pulled to opposite poles of the cell.
