1
Q

Interphase

A

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

2
Q

Mitosis

A

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

3
Q

Prophase

A

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

4
Q

Metaphase

A

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

5
Q

Anaphase

A

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
Q

Telophase

A

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

7
Q

Cytokinesis

A

Final stage where cytoplasm divides

8
Q

Chromosomes

A

Bundled up chromatin in the nucleus

9
Q

Centromere

A

Joins sister chromatids at the center

10
Q

DNA

A

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

11
Q

Cancer

A

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

12
Q

Benign

A

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

13
Q

Malignant

A

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

14
Q

Cell cycle

A

Regular cycle of growth

15
Q

Radiation treatment

A

Treatment of disease using XD-rays

16
Q

Chemotherapy

A

Treatment of disease by the use of chemical substances

17
Q

Where is DNA found

A

Chromatin of the nucleus

18
Q

What are the four kinds of nitrogen bases

A

Adenine
Guanine
Thymine
Cytosine

19
Q

What is formed during DNA replication

A

Two new identical strands

20
Q

What is the 5-carbon sugar called

A

Deoxyribose

21
Q

Guanine pairs with

A

Cytosine

Apple trees can grow

22
Q

Metaphase

A

Chromosomes line up across the center of the cell

Each chromosome is connected to a spindle fiber

23
Q

Prophase

A

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

24
Q

Anaphase

A

Sister chromatids seperate into individual chromosomes

Individual chromosomes seperate

25
Q

Telophase

A

Two nuclear envelope form

26

27
Q

Causes of cancer

A

Cigarette smoke
Water and air pollution
Ultraviolet radiation from the sun

28
Q

What’s the difference between benign and malignant tumors

A

Benign tumors remain at original site and malignant tumors spread

29
Q

Metastasis

A

Spreading of cancer cells into other parts of the body

30
Q

PMAT

A

Prophase
Metaphase
Anaphase
Telophase

31
Q

What stage does Cytokinesis Occur during

A

Third

32
Q

What shape is a DNA molecule

A

Long twisted ladder

33
Q

SPF

A

Sun protection factor
