Question 1

What are the 3 main stages of the cell cycle

Answer 1

Interphase, Mitosis, and Cytokinesis

Question 2

What are the stages of Interphase

Answer 2

G1, S, and G2

Question 3

What are the stages of Mitosis

Answer 3

Prophase, Metaphase, Anaphase, and Telophase

Question 4

“Disorganized” DNA in the nucleus during interphase

Answer 4

Chromatin

Question 5

A condensed, X-shaped piece of DNA

Answer 5

Chromosome

Question 6

Structure that is made of the centrioles and many microtubules

Answer 6

Spindle Apparatus

Question 7

A structure that connects two chromatids to each other

Answer 7

Centromere

Question 8

A chromosome that has two of these which are identical to each other

Answer 8

Chromatid

Question 9

The area of the cell which is indented as one cell starts to split into two cells

Answer 9

Furrow

Question 10

What is the difference between Cytokinesis and Mitosis

Answer 10

Cytokinesis is division of the whole cell, Mitosis is division of the nucleus

Question 11

Why must DNA be replicated after Cytokinesis

Answer 11

So there is enough to redo the duplication process and to make another centriole

Question 12

What happens in G1

Answer 12

The cell grows and prepares to copy the DNA, there is also a checkpoint to see if the DNA is damaged

Question 13

What happens in the S phase

Answer 13

The cells DNA is replicated, which makes a second chromatid for each chromosome, and there is a checkpoint to see if the DNA is replicating correctly

Question 14

What happens in G2

Answer 14

The ribosomes make tubulin so the cell can make microtubules during Mitosis and there is a checkpoint to see if all the DNA has been replicated

Question 15

What happens in Prophase

Answer 15

Chromatin condenses into chromosomes, the nucleus dissolves, and the centrioles move towards opposite poles, begin growing spindle fibers that then attach to all the chromosomes at the centromere

Question 16

What happens in Metaphase

Answer 16

Motor proteins pull the chromosomes to the center of the cell and a checkpoint makes sure they are attached to the spindle fibers properly

Question 17

What happens in Anaphase

Answer 17

The spindle fibers pull the chromosomes apart

Question 18

What happens during Telophase

Answer 18

The chromosomes arrive at opposite pulls where they are turned back into chromatin, then a nuclei reforms around both groups of DNA

Question 19

Microtubules used by the Centrioles to pull the chromosomes apart during Mitosis

Answer 19

Spindle Fibers

Question 20

What happens during Cytokinesis

Answer 20

A furrow forms and deepens until the cell splits into 2 cells with identical nuclei
