Mitosis/Meiosis Test

Question 1

Explain how sexual reproduction results in unique offspring.

Answer 1

Haploid gets a mixing of the maternal and paternal DNA, chromosomes are shifted. They are split, and you combine your sex cells with someone else’s to make a new form of DNA.

Question 2

When does DNA Replication happen in meiosis?

Answer 2

Before meiosis begins.

Question 3

What are the 2 cell divisions of meiosis called?

Answer 3

Meiosis I and IIq

Question 4

What happens during Prophase I?

Answer 4

One chromosome is maternally derived and another is paternally derived. The nuclear envelope breaks down as well. The chromosomes exchange genetic material and microtubules attach to the chromosomes.

Question 5

What happens during crossing over?

Answer 5

The chromosomes exchange genetic material and microtubules attach to the chromosomes.

Question 6

When, during which stage, does crossing over occur in meiosis?

Answer 6

Prophase I

Question 7

How is Metaphase I different from the metaphase of mitosis?

Answer 7

In Metaphase I, you are separating pairs of chromosomes. In mitosis, the chromosomes line up during metaphase.

Question 8

What happens during Anaphase I?

Answer 8

Chromosomes from each pair move to opposite poles of the cell

Question 9

What stage comes after Anaphase I?

Answer 9

Telophase I

Question 10

In Prophase II, each cell is a _____

Answer 10

haploid

Question 11

What happens in Metaphase II?

Answer 11

The chromosomes have lined up on the equatorial plate.

Question 12

What happens in Anaphase II?

Answer 12

When chromatids are separated from each other.

Question 13

What happens in Telophase II?

Answer 13

Chromosomes decondense and nuclear membranes reform.

Question 14

How many cells are produced at the end of meiosis?

Answer 14

4

Question 15

Are the cells produced during meiosis identical to each other? Explain.

Answer 15

No, they are half-identical

Question 16

Which mitosis phase is when chromatin condenses into chromosomes?

Answer 16

Prophase

Question 17

What mitosis phase is when chromosomes line up in the center of the cell.

Answer 17

Metaphase

Question 18

Longest Part of the Cell cycle

Answer 18

Interphase

Question 19

Part of mitosis when Nuclear envelope breaks down

Answer 19

Prometaphase

Question 20

When the cell cleaves into two daughter cells.

Answer 20

Cytokinesis

Question 21

Part of mitosis when chromosomes arrive at the poles.

Answer 21

Telophase

Question 22

Part of mitosis when chromatids are pulled apart.

Answer 22

Anaphase

Question 23

How many chromosomes are visible at the beginning of mitosis?

Answer 23

4

Question 24

How many are in each daughter cell at the end of mitosis?

Answer 24

4

Question 25

What happens to the centrioles during mitosis?

Answer 25

They go to the poles of the cell.

Question 26

What are the 5 major phases of a cell life cycle?

Answer 26

Interphase, Prophase, Metaphase, Anaphase, Telophase

Question 27

What are kinetochores? When are they formed?

Answer 27

Kinetochores are the place that on a chromosome that a spindle fiber attaches to during prophase and metaphase.

Question 28

How long does mitosis take?

Answer 28

Several hours

Question 29

Why are most cells in Interphase?

Answer 29

It’s the cell’s resting place.
