Cell Communication/Cell Cycle

Check points/communication

100

This checkpoint checks to make sure that DNA has been replicated properly.

G2

200

This cell cycle checkpoint makes sure that chromosomes have lined up correctly.

M checkpoint

300

Phosphorylation happens by proteins known as __________.

kinase

400

These Displace GDP with GTP to activate enzyme (cellular response) 

G cprs

500

The endocrine system sends out hormones which travel

long distance

cell cycle

100

Cells produce this molecule which increases in conc. during interphase. What is this?

cyclin

200

Before a cell can enter mitosis, it must spend a large majority of its life in what phase?

interphase

300

What is the special enzyme used by cells to regulate the cell cycle?

cyclin dependent kinase

400

This phase of the cell cycle involves the replication of DNA.

s phase

500

How many chromosomes would there be during prophase in a cell that has 10 chromosomes in G1?

10

cell communication

100

Hormones and pheromones use what type of cellular communication?

endocrine

200

The nervous system uses ______ to move electrical (charged molecule) messages through the body.

ION channel pathway

300

The signal transduction pathway must first start with signal molecules.  What do we call these?

ligands

400

This specialized pathway can activate one enzyme with one signal molecule.  What is this?

G- protein pathway

500

Cyclic AMP is an example of this type of molecule that allows for responses to be amplified.

secondary messenger

cell division

100

This process results in the formation of new prokaryotic cells.

binary fission

200

What do we call the cells that result from eukaryotic cell division?

daughter cells

300

Before a cell can divide, DNA must be condensed and coiled into what structures?

chromosomes

400

What type of cells must go through one cellular division in order to produce diploid cells?

somatic body cells

500

If you start with 2 cells and each went through mitosis 3 times, how many cells are there?

16

cancer

100

When cells can no longer be regulated by the cell cycle, they are considered what?  

CANCEROUS

200

Cancer cells can move throughout the body to form new tumors.  The lack of what allows this?

anchorage dependence

300

This process describes what happens when a cancer or tumor spreads through the body.

metastasize

400

These evade apoptosis and continue dividing with errors

cancer cells

500

Cancer cells are able to form large tumors due to the fact that they do not exhibit what?

density dependent and anchorage dependence
