Flashcards in Cell Cylcle Test Deck (34):
1

Interphase

Phase where cell grows, makes a copy of its DNA and prepares to divide into 2 cells

2

Mitosis

Stage where the cells nucleus divides into 2 nuclei and produces two daughter cells

3

Prophase

First and longest stage were chromatin bundles to form chromosomes. Nucleus disappears and spindles form

4

Metaphase

Second stage where all the chromosomes are pulled to the center of the cell

5

Anaphase

Third stage where sister chromatids separate and each chromatid is now a daughter
Spindles, shortens, and splits chromatids to opposite sides of the cell

6

Telophase

Chromatids move to opposite sides of the cell and two new nuclei are formed

7

Cytokinesis

Final stage where cytoplasm divides

8

Chromosomes

Bundled up chromatin in the nucleus

9

Centromere

Joins sister chromatids at the center

10

DNA

Genetic material that carries info about an organism from one generation to the next

11

Cancer

Disease caused by disruption to the cell cycle leading to uncontrolled cell division

12

Benign

Abnormal mass of essentially normal cells that always remain at site and can be removed w/surgery

13

Malignant

Mass of cancerous cells that displace normal tissue as it grows
Can spread

14

Cell cycle

Regular cycle of growth

15

Radiation treatment

Treatment of disease using XD-rays

16

Chemotherapy

Treatment of disease by the use of chemical substances

17

Where is DNA found

Chromatin of the nucleus

18

What are the four kinds of nitrogen bases

Adenine
Guanine
Thymine
Cytosine

19

What is formed during DNA replication

Two new identical strands

20

What is the 5-carbon sugar called

Deoxyribose

21

Guanine pairs with

Cytosine
Apple trees can grow

22

Metaphase

Chromosomes line up across the center of the cell
Each chromosome is connected to a spindle fiber

23

Prophase

Centrioles separate
Chromosomes become visible
Nucleus disappears and nuclear envelope breaks down

24

Anaphase

Sister chromatids seperate into individual chromosomes
Individual chromosomes seperate

25

Telophase

Two nuclear envelope form

27

Causes of cancer

Cigarette smoke
Water and air pollution
Ultraviolet radiation from the sun

28

What's the difference between benign and malignant tumors

Benign tumors remain at original site and malignant tumors spread

29

Metastasis

Spreading of cancer cells into other parts of the body

30

PMAT

Metaphase
Anaphase
Telophase

31

What stage does Cytokinesis Occur during

Third
