Mitosis + Meiosis

Question 1

What is the best explanation for why chromosomes line up in the center of the cell before starting to split apart during mitosis.

Answer 1

To make sure each daughter cell gets the correct amount of DNA.

Question 2

Centromeres divide in which phase of mitosis

Answer 2

Anaphase

Question 3

The nuclear envelope breaks down in ______ during mitosis

Answer 3

Prophase

Question 4

What happens during meiosis 1

Answer 4

Homologous chromosomes separate into two different cells

Question 5

What happens before meiosis occurs (pre-meiosis)

Answer 5

DNA replicates

Question 6

Which of these events occur during Meiosis 2:
A. DNA replicates
B. Homologous chromosomes separate into two cells
C. Replicated chromosomes are separated into sister chromatids and segregated into daughter cells

Answer 6

C.

Question 7

What is the difference between the parent cell (pre-meiosis) and one of the four daughter cells

Answer 7

The daughter cells have half as much genetic information as the parent cell; one copy of each chromosome instead of a pair of each chromosome

Answer 8

Meiosis 1

Answer 9

After meiosis 1

Answer 13

Centrioles

Question 14

Answer 14

Prophase

Question 15

What is the phase of mitosis in which spindle fibers attach to the centromeres of sister chromatids

Answer 15

Metaphase

Question 16

What is the stage of mitosis in which chromosomes uncoil and spindle fibers break down

Answer 17

Telophase

Question 18

Which stage of meiosis occurs first

Answer 18

Prophase 1

Question 19

During Prophase 1, chromosomes from each parent pair up based on their similarity. These paired chromosomes are called _______.

Answer 19

Homologous

Question 23

Crossing over occurs in what stage of meiosis

Answer 23

Prophase 1

Question 24

What are the phases of meiosis in order

Answer 24

Prophase 1, metaphase 1, anaphase 1, telophase 1, cytokinesis (end of meiosis 1), prophase 2, metaphase 2, anaphase 2, and telophase 2 and cytokinesis (end of meiosis 2)
