Q

Interphase

A

“Resting phase”: Cells are
getting ready to divide
G1 phase: cells grow
S phase: chromosomes replicated and DNA molecules synthesized
G2 phase: produces organelles needed for cell division
If a cell fails checkpoints, cell will go through apoptosis

16
Q

Anaphase

A

Chromosomes separate into Sister Chromatids and

are pulled to opposite ends of the cell

17
Q

Telophase

A

Cell membrane starts to pinch together

nucleus divides and nuclear envelope starts to reform

18
Q

Cytokinesis Plant:

A

cytokinesis begins when a new cell wall forms between the two new cells

19
Q

Cytokinesis Animal:

A

The two new cell pinch and pull apart

20
Q

Cyclin:

A

protein that regulates the timing of the cell cycle in eukaryotic cells

21
Q

Internal Regulators

A

proteins that respond to events inside the cell

Ex: one type of regulator doesn’t allow cell to enter mitosis until all chromosomes have been replicated

22
Q

External Regulators

A

proteins that respond to events outside the cell.

direct cells speed up or slow down the cell cycle

23
Q

Cancer cells do not…

A

respond to the signals that regulate the growth of most cells.

24
Q

Cancer cells…

A

divide uncontrollably cell and form masses of cells called tumors

25
Q

Stem cells:

A

unspecialized cell that have the potential to differentiate

26
Q

Differentiate:

A

make or become specialized in the process of growth or development

27
Q

in bone marrow…

A

stem cells produce more than a dozen types of blood cells
