AP Cell Communication and Cell Cycle Review

Cell Cycle 1

100

A condensed chromosome is only seen during this part of the cell cycle

What is the mitotic phase (mitosis ok)

200

If a parent cell were to have 10 chromosomes, each daughter cell would have this many after mitosis.

What is 10?

300

The phase of mitosis in which the nucleus disappears.

What is prophase?

400

This is how bacteria divide.

What is binary fission?

500

this begins to form when two animal cells divide at the end of mitosis.

what is a cleavage furrow

Cell Cycle 2

100

The process by which cytoplasm is divided into two nearly equal parts between the divided nuclei. 

What is cytokinesis ?

200

This stage of the cell cycle is when DNA is replicated. 

What is the S stage?

300

The 3 steps of interphase 

What are G1, S, G2? 

400

Two new nuclei form during this stage of mitosis.

What is Telophase?

500

This is the point in the cell cycle where the sister chromatids separate.

What is Anaphase?

Cell Cycle Regulation 1

100

This is the percent time the cell spends in interphase.

90%

200

These are the 3 checkpoints in a cell cycle

G1 checkpoint, G2 checkpoint, M checkpoint

300

Cyclins bind to this protein in order to move the cell to the next part of the cycle

CDK (cyclin dependent kinase)

400

Cell density, growth factors, DNA, and size are checked during this checkpoint.

What is G1

500

This protein is can bind to a cyclin CDK complex OR can proofread and correct DNA.

What is p53?

Cell Cycle Regulation 2

100

This condition can be caused by the accumulation of mutations in genetic material and uncontrolled cell growth. 

What is cancer?

200

The family of proteins that control the progression of cells through the cell cycle. (will degrade after being used)

What is a cyclin?

300

This is the name for controlled cell death. 

What is apoptosis?

400

This checkpoint decides whether or not the cell will undergo division or enter the G₀ phase. 

What is G1?

500

At this checkpoint, the cell pauses to see if the spindle fibers are attached correctly and all chromosomes are in the middle of the cell. 

What is the M or spindle checkpoint?

Miscellaneous

200

this begins to form between two plant cells at the end of mitosis

what is a cell plate?

300

This gene codes for proteins that inhibit the cell cycle

What is a tumor suppressor gene?

400

This gene codes for proteins that promote the cell cycle

What is a proto-oncogene

500

These genes are associated with cancer

What are oncogenes?
