Mitosis

Question 1

DNA

Answer 1

Genetic material that organisms inherit from their parents.

Question 2

Chromatin

Answer 2

Uncondensed chromosomes

Question 3

Chromosome

Answer 3

Contains DNA; is found in the nucleus and consists of thread-like proteins.

Question 4

Chromatid

Answer 4

One of two identical ¨sister¨ parts of a duplicated chromosome.

Question 5

Centromere

Answer 5

Constricted region of a chromosome that separates into a short arm and long arm.

Question 6

Centrioles

Answer 6

Paired barrel-shaped organelles located in the cytoplasm of animal cells that make spindle fibers.

Question 7

Spindle fibers

Answer 7

Structures that attach to centromere during cell division.

Question 8

Diploid

Answer 8

Refers to a cell that contains two sets of homologous chromosomes.

Question 9

Cell cycle

Answer 9

Series of events that contains two sets of homologous chromosomes.

Question 10

Cell cycle

Answer 10

Series of events in which a cell grows prepares for cell division and divides to form two daughter cells.

Question 11

Cell cycle

Answer 11

Series of events in which a cell grows prepares for cell division and divides to form two daughter cells.

Question 12

Interphase

Answer 12

Resting phase or period of the cell cycle during cell division.

Question 13

Mitosis

Answer 13

Part of eukaryotic cell division during which the cell nucleus divides.

Question 14

Prophase

Answer 14

First and longest phase of mitosis chromosomes duplicate and condense and become visible. Nuclear membrane begins to dissolve.

Question 15

Metaphase

Answer 15

Second phase of mitosis. Chromosomes line up across the middle of the cell along the metaphase plate.

Question 16

Anaphase

Answer 16

Third phase of mitosis. Chromosomes are pulled apart by the spindle fibers, separate at the centromere and migrate to opposite ends of the cell.

Question 17

Telophase

Answer 17

Final phase of mitosis where a cleavage furrow forms (in animal cells)and distinct chromosomes begin to tangle into chromatin and the nuclear membrane begins to re-appear in tow distinct daughter cells.

Question 18

Cytokenesis

Answer 18

The complete division of the cytoplasm during cell division to form two separate daughter cells.

Question 19

Cell plate

Answer 19

A structure that forms in the cell od land plants while they are undergoing cell division from telophase.

Question 20

Cleavage furrow

Answer 20

An indentation that in a cells surface when the cell is preparing to divide during telophase in cell division.

Question 21

Cancer

Answer 21

Uncontrolled cell division and growth that results in a tumor

Question 22

Mutation

Answer 22

Any change in DNA or the genetic material of a cell.

Question 23

Mutagen

Answer 23

A chemical or physical agent that can cause a mutation.

Question 24

Oncogene

Answer 24

A mutated gene that contributes to the development of cancer.
