Cell Cycle and Mitosis

Cycles of Cell Cycle

100

enzyme that proteins bind to that help with activities in the cell cycle

cyclin-dependent kinASE

200

What is the longest phase in the cell cycle?

Interphase

300

The cell cycle results in two genetically _________ cells.

Identical

400

State which phase in the cell cycle the cell grows to its full size, copies the DNA and organelles and prepares for cell division

Interphase

500

Double Jeopardy-

What is the importance of the cell cycle to multicellular organisms with respect to tissue repair? And what happens when cells grow uncontrollably?

The cell cycle replaces damaged, worn, and aging cells.

Cancer

General Mitosis

100

How many phases make up mitosis? List them and provide a mnemonic device to help you remember

4

200

True or False: Cytokinesis is included in the 4 phases of mitosis.

False

300

True or False: Apoptosis is programmed cell death

True

400

What is the end product of mitosis?

one cell with 2 nuclei

500

Illustrate a cell in each of the stages of mitosis and explain what is occurring within the cell during that stage

Prophase (pair), Metaphase (middle), Anaphase (apart), Telophase (two nuclei)

Interphase

100

What substage of the cell cycle prepares the cell for division?

G2

200

Double Jeopardy-

During ___________, DNA has replicated and appears as a loosely coiled mass known as chromatin.

interphase (synthesis)

300

Is the nuclear membrane still intact during interphase?

Yes

400

During interphase, ________________ is replicated.

DNA

500

List the three parts of interphase and explain what occurs within the cell during each stage

G1 (cell growth), S (synthesis), G2 (preparation for cell division)

Cell Division

100

protein that binds to enzymes in the cell cycle to start various activities

cyclin

200

At which phase do the chromosomes become visible in the cell (x shaped structures form)?

Prophase

300

In which phase do the 2 nuclear envelopes reform around the separated chromosomes (still one cell)?

Telophase

400

At what phase in cell division do the spindle fibers pull the chromosomes to opposite poles of the cell?

Anaphase

500

Spindle fibers attach to the centromeres and chromosomes line up in the middle of the cell during this phase of cell division.

Metaphase

Cytokinesis

100

The division of the cytoplasm of the cell during cell division is referred to as_____________.

Cytokinesis

200

What is the end result of cytokinesis?

Two identical daughter cells

300

True or False: Cytokinesis is the division of the cell nucleus.

False. Cytokinesis is the division of the cytoplasm. Mitosis is the division of the nucleus.

400

Double Jeopardy-

The pinching apart of the cytoplasm in a(n) _______ cell creates a cleavage furrow

animal

500

In plant cells, a _______________ is formed between the two daughter cells as they pull apart during cytokinesis.

Cell plate
