Cell Cylcle Test

Question 1

Interphase

Answer 1

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

Question 2

Mitosis

Answer 2

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

Question 3

Prophase

Answer 3

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

Question 4

Metaphase

Answer 4

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

Question 5

Anaphase

Answer 5

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

Question 6

Telophase

Answer 6

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

Question 7

Cytokinesis

Answer 7

Final stage where cytoplasm divides

Question 8

Chromosomes

Answer 8

Bundled up chromatin in the nucleus

Question 9

Centromere

Answer 9

Joins sister chromatids at the center

Question 10

DNA

Answer 10

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

Question 11

Cancer

Answer 11

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

Question 12

Benign

Answer 12

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

Question 13

Malignant

Answer 13

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

Question 14

Cell cycle

Answer 14

Regular cycle of growth

Question 15

Radiation treatment

Answer 15

Treatment of disease using XD-rays

Question 16

Chemotherapy

Answer 16

Treatment of disease by the use of chemical substances

Question 17

Where is DNA found

Answer 17

Chromatin of the nucleus

Question 18

What are the four kinds of nitrogen bases

Answer 18

Adenine
Guanine
Thymine
Cytosine

Question 19

What is formed during DNA replication

Answer 19

Two new identical strands

Question 20

What is the 5-carbon sugar called

Answer 20

Deoxyribose

Question 21

Guanine pairs with

Answer 21

Cytosine

Apple trees can grow

Question 22

Metaphase

Answer 22

Chromosomes line up across the center of the cell

Each chromosome is connected to a spindle fiber

Question 23

Prophase

Answer 23

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

Question 24

Anaphase

Answer 24

Sister chromatids seperate into individual chromosomes

Individual chromosomes seperate

Question 25

Telophase

Answer 25

Two nuclear envelope form
