QuestionAnswer
Cell cycle process of cellular reproduction, occurring in three main stages
Chromatin relaxed form of dna in the nucleus of a cell
Chromosome dna-containing structure that carries genetic material from one generation to another
Cytokinesis third main stage of the cell division by stimulating production of proteins required for mitosis
Interphase first stage of the cell cycle, during which a cell grows, matures and replicates its dna
Mitosis second main stage of the cell cycle during which the cell's replicate dna divides and two genetically identical diploid daughter cells are produced
Anaphase third stage of mitosis in which sister chromatids are pulled apart and microtublues, along with motor proteins move the chomosomes to opposite poles of the cell
Centromere cell structure that joins two sister chromatids
Metaphase second stage of mitosis in which motor proteins pull sister chromatids to the cell's equator
Prophase first stage of mitosis, during which the cell's chromatin condenses into chromosomes
Sister chromatid structure that contains identical dna copies and formed during dna replication
Spindle apparatus structure made of spindle fibers, centrioles, and aster fibers that is involved in moving and organizing chromosomes before the cell divides
Telophase last stage of mitosis in which nucleoli reappear.  Two new nuclear memberanes begin to form, but the cell has not yet completely divided
Apoptosis programmed cell death
Cancer uncontroled  growth and division of cells that can be caused by changes in control of the cell cycle and also may be caused by environmental factors 
Carcinogen cancer-causing substance
Cyclin one of the specific proteins that regulate the cell cycle
Stem cell unspecialized cell that can develop into a specialized cell under the right conditions
dependent kinase enzyme to which cyclin binds during interphase and mitosis, triggering and controlling activities during the cell cycle

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
