Question 2

The fusion of parent cells to create an offspring that will inherit some genetic information from each parent cell

Answer 2

Sexual reproduction

Question 3

Packages of DNA

Answer 3

Chromosomes

Question 4

The bond between proteins and chromosomes

Answer 4

Chromatin

Question 5

The series of events a cell goes through as they grow and divide

Answer 5

Cell cycle

Question 6

The period of growth that a cell goes through, it’s everyday life

Answer 6

Interphase

Question 7

The phase when cells do most of their growing, the cells synthesize their proteins and organelles

Answer 7

G1 phase

Question 8

During this phase DNA is synthesized and chromosomes are replicated, at the end of this phase the cell contains twice as much DNA as it did in the beginning

Answer 8

S phase

Question 9

During this phase many of the organelles and molecules needed for cell division are produced

Answer 9

G2 phase

Question 10

During this phase cell division takes place

Answer 10

M phase

Question 11

The division of the nucleus

Answer 11

Mitosis

Question 12

The division of the cytoplasm

Answer 12

Cytokinesis

Question 13

During this phase of mitosis the DNA condenses and duplicated chromosomes become visible, the mitotic spindle also begins to form

Answer 13

Prophase

Question 14

The area where chromatids are attached

Answer 14

Centromere

Question 15

Each DNA strand in the duplicated chromosome

Answer 15

Chromatid

Question 16

An organelle that helps with the mitotic spindle

Answer 16

Centriole

Question 17

The phase when the centromeres of line up across the center of the cell, the spindle fibers connect the centromeres to the two poles of the spindle

Answer 17

Metaphase

Question 18

During this phase the chromatids separate becoming single chromosomes, they move along the spindle fibers to opposite ends of the cell

Answer 18

Anaphase

Question 19

During this phase chromosomes begin spread into a tangle of chromatin

Answer 19

Telophase

Question 20

Proteins that regulate the cell division process

Answer 20

Cyclins

Question 21

Proteins that regulate the events occurring inside the cell

Answer 21

Internal regulators

Question 22

Proteins regulating the events occurring outside the cell

Answer 22

External regulators

These stimulate the growth and division of cells

Answer 23

Growth factors

Question 24
