Cell Cycle and Mitosis

Question 1

Which phase of the cell cycle do cells spend most of their time?

Answer 1

Interphase

Question 2

During which phase do you first see chromosomes condense?

Answer 2

Prophase

Question 3

During which phase do chromosomes line up along the middle of the cell?

Answer 3

Metaphase

Question 4

During which phase will the nucleus break down?

Answer 4

Prophase

Question 5

During which phase will the sister chromatids be separated?

Answer 5

Anaphase

Question 6

During which phase will two nuclei be seen?

Answer 6

Telophase

Question 7

True or False: A plant cell pinches off its cytoplasm during cytokinesis

Answer 7

False! A plant cell forms a new cell wall between the two new cells

Question 8

Why does an organism need to undergo mitosis?

Answer 8

To grow, repair and sometime reproduce (in asexually reproducing organisms)

Question 9

If cells grew large rather than dividing, what would be a potential problem?

Answer 9

They could not efficiently move materials in and out of the cell

Question 10

DNA is copied during what phase?

Answer 10

S phase

Sister chromatids are what?

Answer 11

Identical copies of a chromosome

Answer 12

Chromatin

Question 13

What is the name of the protein around which DNA coils?

Answer 13

Histones

What moves the chromosomes during mitosis?

Answer 14

Spindle fibers

Question 15

How many chromosomes do humans have?

Answer 15

46

Question 16

Sister chromatids are connected where?

Answer 16

Centromere

Question 17

What is the final result of the cell cycle?

Answer 17

Two identical daughter cells

Question 18

What 3 phases make up interphase?

Answer 18

G1, S and G2

Question 19

What is a cell doing during interphase?

Answer 19

Growing, making new organelles, producing proteins, synthesizing DNA and preparing to divide
