Q

When chromosomes become visible at the beginning of cell division what does each chromosome consist of

A

Two identical sister chromatids

18
Q

The chromosomes move until the form two groups near the poles of the spindle
what phase is this

A

Anaphase

19
Q

Two reasons why cells divide rather than continue to and grow in definitely

A

It will have trouble moving nutrients and waste across cell membrane’s and there will be an information crisis

20
Q

What happens during the S phase

A

The replication of chromosomes take place

21
Q

Cancer so don’t respond to signal that regulate…

A

Growth of most cells

22
Q

What is cell division

A

The process in which a cell divides into two new daughter cells

23
Q

Interphase is divided into 3 phases

A

G1, S, G2

24
Q

What happens during the G1 phase

A

Cells increase in size in make new proteins and organelles

25
Q

A nuclear envelope reforms around each cluster of chromosomes the nucleolus becomes visible in each daughter nucleus
What phase is this

A

Telophase

26
Q

What are the four phases of mitosis

A

Prophase metaphase anaphase and telophase

27
Q

What happens to cells at the edges of an injury wanna cut in the skin or breaking in a bone occurs

A

It divides rapidly

28
Q

What form is the midway between the divided nucleus during cytokinesis in plant cells

A

The cell plate

29
Q

What is the cell cycle

A

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

30
Q

The chromosomes become visible. The centrioles take up positions on opposite sides of the nucleus
What phase is this

A

Prophase

31
Q

Each pair is chromatids is attached an area called the….

A

Centromere

32
Q

When a cell increases in size does it make extra copies of it DNA

A

No

33
Q

What determines the rate at which food and oxygen in the cell are used up and waste products produced

A

The cells volume

34
Q

The chromosomes line up across the center of the cell

What phase is this

A

Metaphase

35
Q

What happens to the rapidly dividing cells when the healing process nears completion

A

Cell division rate slows to normal

36
Q

If a cell grows in size does it’s volume increases much more rapidly than its surface area

A

Yes

37
Q

What 2 facts are true about external regulators

A

They direct sales to speed up or slow down the cycle and they include growth factors

38
Q

What are the two tiny structures located in the cytoplasm use a nuclear envelope at the beginning of prophase

A

Centrioles

39
Q

What is cancer

A

A disorder in which some of the bodies own cells lose the ability to control their growth

40
Q

What happens in the G2 phase

A

Many of the organelles and molecules required for cell division are reproduced
