Meiosis & Genetics

Question 1

How many Daughter cells do you end up with at the end of Meiosis 2?

Answer 1

Four Daughter cells.

Question 2

When does crossing over occur?

Answer 2

Prophase 1

Question 3

When do chromosomes line up in a single file?

Answer 3

Metaphase 2

Question 4

When does DNA replication take place?

Answer 4

Interphase

Question 5

Were during Meiosis 2 do chromosomes line up against?

Answer 5

The Cell’s equator

Question 6

What happens in Telophase 1?

Answer 6

Cytoplasm divides and 2 daughter cells are formed

Question 7

How many cell division are there in Meiosis?

Answer 7

Two cell divisions

Question 8

What happens during Anaphase 1?

Answer 8

Chromosomes move to opposite poles of the cell

Question 9

Meiosis consists of what two cell divisions?

Answer 9

Meiosis 1 and Meiosis 2

Question 10

What happens in Prophase 2?

Answer 10

Spindle fibers attach to centromers

Question 11

What is Meiosis?

Answer 11

It is the process of reduction division in which the number of chromosomes per cell is cut in half throughout the separation of homologous chromosomes in a diploid cell.

Question 12

What are the two different Meiotic divisions called?

Answer 12

Meoisis 1 and Meiosis 2.

Question 13

Cell Cycle

Answer 13

is the entire series of events cells go through when they divide

Question 14

Mitosis

Answer 14

is the process of the division of the nucleus in eukaryotic cells (body cells only). Usually includes four stages: prophase, metaphase, anaphase, and telophase.

Question 15

Prophase

Answer 15

is the 1st and longest phase of mitosis. Chromosomes become visible. The centrioles separate and move to opposite sides of the cell. Chromosomes become attached to fibers in the spindle at the centromere. Chromosomes coil more tightly. Nucleolus disappears. Nuclear envelope breaks down.

Question 16

Metaphase

Answer 16

is the 2nd stage of mitosis. Often lasts only a few minutes. Chromosomes line up across the center of the cell. Microtubules connect the centromere of each chromosome to the two poles of the spindle

Question 17

Anaphase

Answer 17

is the 3rd stage of mitosis, in which the chromatids of each chromosome have separated and the daughter chromosomes are moving to the poles of the cell.

Question 18

Telophase

Answer 18

is the 4th and final stage of mitosis, in which daughter nuclei are forming and cytokinesis has typically begun.

Question 19

Cytokinesis

Answer 19

The division of the cytoplasm to form two separate daughter cells immediately after mitosis.

Question 20

Cell Division

Answer 20

is the division of one cell into two. The reproduction of new cells.

Question 21

Chromosomes

Answer 21

carry genetic material, found in the nucleus of eukaryotic cells.

Question 22

Chromatin

Answer 22

granular material visible within the nucleus; consists of DNA tightly coiled around proteins

Question 23

Chromatid

Answer 23

one of two identical “sister” parts of a duplicated chromosome attached at the centromere. While joined, they make up one chromosome. These are separated during mitosis.

Question 24

Centromere

Answer 24

Where the sister chromatids are attached to form one chromosome.

Question 25

interphase

Answer 25

Stage in the cell cycle when the cell is not dividing. Cells grow, chromosomes and organelles are duplicated and cells grow more. G1, S, G2

Question 26

asexual reproduction

Answer 26

A type of reproduction involving only one parent that produces genetically identical offspring. Ex. how body cells divide

Question 27

S Phase

Answer 27

The synthesis of DNA during the cell cycle; the portion of interphase during which DNA is replicated.

Question 28

G2 Phase

Answer 28

The second growth phase of the cell cycle during interphase after DNA synthesis occurs.

Question 29

cell plate in plant cells

Answer 29

the midline of a dividing plant cell. Where the new cell wall forms during cytokinesis.

Question 30

G1 Phase

Answer 30

The first growth phase of the cell cycle during interphase before DNA synthesis occurs.
