Lets Warm Up

#1.	Lets warm you up: Which of the following is true of mitosis in a diploid cell?
	a.	It results in 2 haploid daughter cells.
	b.	It involves replication of the cell's DNA.
	c.	It results in daughter cells who are genetically identical, but physically smaller, than the original cell.
	d.	Bill Gates has way more money than all the employees and students at GRCC combined.

#2.	From here on in, anything is fair game. Ready? Is crossing over (swapping of segments of DNA between homologous chromosomes) seen with mitosis?
	a.	Yes, it is a normal part of mitosis.
	b.	No, crossing over is not associated with mitosis.
	c.	Yes, but it only occurs in fetal cells.
	d.	None of those above.

#3.	During which stage does DNA replication occur?
	a.	Prophase.
	b.	Anaphase.
	c.	Metaphase.
	d.	None of those above.

#4.	Which stage of mitosis is seen in the pictured cell?
	a.	Anaphase.
	b.	Prophase.
	c.	Telophase.
	d.	Interphase.

#5.	At what phase in the cell cycle does DNA replication occur?
	a.	G1.
	b.	S.
	c.	G0.
	d.	M.

#6.	Which of the following is NOT correct?
	a.	Mitosis is produces genetically identical cells.
	b.	Cytokinesis is a part of mitosis
	c.	Metaphase occurs before anaphase.
	d.	All somatic cells are produced by mitosis.

#7.	What is the function of centrioles?
	a.	To cause cytokinesis via the concentric shortening of microtubules.
	b.	They are required for DNA replication.
	c.	They are the structure which hold the 2 daughter chromatids together at the centromere.
	d.	They produce microtubules for the chromosomes to migrate along as they move to opposite poles of the cell.

#8.	What stage of mitosis is this cell in?
	a.	Anaphase.
	b.	Telophase.
	c.	Prophase.
	d.	None of the above stages.

#9.	Which answer gives the stages of mitosis in proper chronological order?
	a.	Anaphase, prophase, metaphase, telophase.
	b.	Metaphase, anaphase, telophase, prophase
	c.	Prophase, metaphase, anaphase, telophase.
	d.	Interphase, prophase, metaphase, anaphase, telophase.

#10.	This is a picture of a cell in telophase.
	a.	Correct.
	b.	No, this is a cell in anaphase.
	c.	No, this is a cell in interphase.
	d.	None of the above choices.

#11.	Which is the correct sequence of stages in the cell cycle that produces a differentiated cell? (D = cell differentiation)
	a.	G1, S, G2, M, D.
	b.	G1, G2, S, M, D.
	c.	S, G1, G2, M, D.
	d.	G1, M, G2, S, D.

#12.	In prophase, the nuclear membrane disappears.
	a.	True, it occurs early in prophase.
	b.	True, it occurs late in prophase.
	c.	False, it is not associated with prophase.

#13.	Match the terms with the appropriate stages in the answer: Migration, Shortening and Thickening, Cytokinesis, Prophase.
	a.	Telophase, Anaphase, Prophase, centrioles forming.
	b.	Anaphase, Prophase, Metaphase, microtubules.
	c.	Anaphase, Prophase, Telophase, centrioles forming.
	d.	Metaphase, Anaphase, Telophase, microtubules.

#14.	Which of the following is correct?
	a.	The chromosomes shorten and thicken during prophase.
	b.	The nucleolus reappears following telophase.
	c.	Interphase is characterized by little cellular activity, as the cell is resting to prepare for the next mitotic event.
	d.	All of the above.

#15.	Place the pictures in the correct chronological order. 1. 2. 3. 4.
