Cell Cycle

Question 1

In this process the cell grows and replicates its DNA and centrioles.

Answer 1

Interphase

Question 2

In this process of Mitosis the chromatin condenses into chromosomes. The centrioles separate, and a spindle begins to form. The nuclear envelope breaks down.

Answer 2

Prophase

Question 3

In this process of Mitosis the chromosomes line up across the center of the cell. Each chromosome is connected to a spindle fiber at its centromere.

Answer 3

Metaphase

Question 4

In this process of Mitosis the sister chromatids separate into individual chromosomes and are moved apart.

Answer 4

Anaphase

Question 5

The chromosomes gather at opposite ends of the cell and lose their distinct shapes. Two new nuclear envelopes will form.

Answer 5

Telophase

Question 6

This process occurs after mitosis finishes, and the cytoplasm divides to form new daughter cells.

Answer 6

Cytokinesis

Question 7

Programmed cell death

Answer 7

Apoptosis

Question 8

A series of events cells go through as they grow and divide.

Answer 8

the cell cycle

Question 9

what are the two phases of the cell cycle?

Answer 9

interphase and cell division

Question 10

What are the three phases interphase is divided into?

Answer 10

G1, S, and G2.

Question 11

This phase in interphase is a period of activity where cells will do most of their growing.

Answer 11

G1

Question 12

This phase in interphase is where chromosomes are replicated and the synthesis of DNA molecules take place.

Answer 12

S phase

Question 13

This phase in interphase many of the of the organelles and molecules required for cell divison are produced.

Answer 13

G2

Question 14

Two tiny structures located in the cytoplasm near the nuclear envelope.

Answer 14

Centrioles

Question 15

A fanlike microtubule structure that helps seperate chromosomes.

Answer 15

Spindle

Question 16

A protein that regulates the timing in a eukaryotic cell.

Answer 16

Cyclin

Question 17

Allows the cell to proceed only when certain processes have happened inside the cell.

Answer 17

Internal Regulator

Question 18

Direct cells to speed up or slow down the cell cycle.

Answer 18

External Regulators

Question 19

A disorder in which the cells have lost the ability to control their own rate of growth and division.

Answer 19

Cancer

Question 20

What is the defect gene in cancer called?

Answer 20

Gene p53

Question 21

What are two types of cancer treatment and what are they?

Answer 21

Radiation-burns/internal lazor

Chemotherapy-iv/chemicals

Question 22

cell membrane is pinched into two equal parts.

Answer 22

animal cells

Question 23

cell plate devlops first, and then a cell wall begins to appear.

Answer 23

plant cells

Question 24

What is the difference and the similiarity between an animal cell and a plant cell?

Answer 24

The cytoplasm divides and the 2 new daughter cells form. The difference is that plant cells develops a cell plate before they start the process.
