Unit 2-Mitosis and Meiosis

Question 1

Mitosis- Interphase

Answer 1

Cell cycle when the cell grows, copies it’s DNA, and prepares to divide.

Question 2

Mitosis- Prophase

Answer 2

Chromatin condenses, nucleus breaks down, centrioles move apart, spindles form

Question 3

Mitosis-Metaphase

Answer 3

Chromosomes are pulled to the center of the cell.

Question 4

Mitosis-Anaphase

Answer 4

Chromosomes are pulled apart at the centromere with each sister chromatid moving to opposite sides of the cell

Question 5

Mitosis-Telophase

Answer 5

Spindle fibers dissolve and the nucleus reforms around each set of chromosomes.

Question 6

Meiosis-Interphase

Answer 6

The cell grows, copies DNA, and prepares to divide

Question 7

Meiosis-Prophase 1

Answer 7

Nucleus breaks down, chromatin condenses into chromosomes, homologous chromosomes pair up, and crossing over occurs

Question 8

Meiosis- Metaphase 1

Answer 8

pairs of homologous chromosomes line up at the center of the cell

Question 9

Meiosis- Anaphase 1

Answer 9

Homologous chromosomes are pulled to opposite sides of the cell.

Question 10

Meiosis- Telophase 1

Answer 10

Spindle fibers dissolve and new nuclei from around the cell.

Question 11

Meiosis- Prophase 2

Answer 11

Nucleus breaks down and chromatin condenses into chromosomes

Question 12

Meiosis-Metaphase 2

Answer 12

When individual chromosomes line up at the center of the cell

Question 13

Meiosis- Anaphase 2

Answer 13

Chromosomes are split at the centromere and the individual chromatids are pulled to opposite sides of the cell

Question 14

Meiosis- Telophase 2

Answer 14

Spindle fibers dissolve and new nuclei from around the chromosomes.

Question 15

Cytokinesis

Answer 15

Cytoplasm divides into 2 or 4 daughter cells

Question 16

Cell cycle

Answer 16

Regular sequence of growth and division that cell undergo

Question 17

Cell cycle (interphase) G1 (Growth) Part 1

Answer 17

The cells are growing and replicating organelles , and carrying out their natural functions.

Question 18

Cell cycle (interphase) G2 (Growth) Part 3

Answer 18

Cells continue normal function and more growth, things must be in order before the next stage.

Question 19

Cell cycle (interphase) S (DNA synthesis) Part 2

Answer 19

Cells are copying their nuclear DNA, before this stage DNA is stored loosely and stage S organizes it in the nucleus in 2 complete DNA sets.

Question 20

Mitosis (M) Part 4

Answer 20

One copy of DNA is distributed into each identical daughter cell

Question 21

Meiosis

Answer 21

Type of cell division where chromosomes number is reduced by half and the daughter cells are genetically distinct from the parents
