Cell Division

Question 1

Cell Division

Answer 1

When a cell is becoming two large, it divides itself into 2 daughter cells.

Question 2

Before Cell Division

Answer 2

The cell replicates all of its DNA. This way, each daughter cell has a complete set of DNA.

Question 3

Mitosis

Answer 3

The first stage of cell division.

Question 4

Cytokinesis

Answer 4

The second stage of cell division

Question 5

Chromosomes

Answer 5

Genetic information from one cell to the next generation of cells is carried by chromosomes

Question 6

Interphase

Answer 6

In between period of growth during cell division

Divided into three phases: G1, S, G2

Question 7

Chromatids

Answer 7

Sisters that make up the chromosomes

Question 8

Centromeres

Answer 8

Each pair of chromatids is attached to an area called the centromere, usually located near the middle of the chromatids

Question 9

Cell Cycle

Answer 9

Series of events that cells go through as they grow and divide

Question 10

G1 Phase

Answer 10

Cells do most of their growing

First phase of cell division

Question 11

S Phase

Answer 11

Chromosomes are replicated, and the synthesis of DNA molecules takes place
Second phase of cell division

Question 12

G2 Phase

Answer 12

Many organelles and molecules required for cell division are produced
Third phase of cell division

Question 13

Mitosis

Answer 13

Four phases:

Prophase, Metaphase, Anaphase, Telophase

Question 14

Prophase

Answer 14

First phase of mitosis

The chromosomes become visible, and the centrioles take up positions on opposite sides of the nucleus.

Question 15

Metaphase

Answer 15

Second phase of mitosis

The chromosomes line up across the center of the cell.

Question 16

Anaphase

Answer 16

Third phase of mitosis
The centromeres split, allowing chromatids to separate and become individual chromosomes

The chromosomes move until they form two groups near the poles of the spindle

Question 17

Telophase

Answer 17

Fourth and final phase of mitosis

A nuclear envelope re-forms around each cluster of chromosomes. The nucleolus becomes visible in each daughter nucleus

Question 18

Spindle

Answer 18

A fan like microtubule structure that helps separate the chromosomes.

Question 19

Cytokinesis

Answer 19

Cytokinesis is when two nuclei, each with a duplicate set of chromosomes, are formed.
