100
What do the chromosomes do during metaphase?
Line up in the center of the cell
100
When during mitosis does the cell lengthen?
During anaphase
100
During what does the cytoplasm and its contents divide into two identical daughter cells?
During cytokinesis
200
What are the two main phases of the cell cycle?

What holds identical pairs of chromosomes together during the S stage?
Centromere
200
Which phase of mitosis is the shortest phase?

About how long does it take a human cell to complete the cell cycle?

24 hours or one complete day

300
During the mitotic phase, what divides first and what divides second?
The nucleus divides first and the cytoplasm divides second.
300
If a person looking thorough a microscpoe sees a cell with something looking like a "plate of spaghetti", what phase of the cell cycle is he looking at?
interphase
300
When do spindle fibers appear?
During prophase
300
During what phase does the copied DNA condense into chromosomes?
During prophase

30

500
What stage of interphase do a cells perform their normal cell functions?
G1
500

What two things disappear during prophase?

Nucleolus and nuclear membrane

500
What happens to the spindle fibers during anaphase?
They shorten, pulling the chromatids towards opposite ends of the cell
500
How long does it take a cell to complete the cell cycle?
It depends on the type of cell it is

It grows or gets larger
