BIO Chapter 12


Why do cells divide? cell growth and development, replace themselves, repair, reproduction
Nuclear division- what goes on in the nucleus
Two types of nuclear division- mitosis and meiosis
Mitosis produces- two genetically identical daughter cells that are also identical to the mother cell
Meiosis produces- one cell gives rise to four daughter cells, each genetically different with half the genetical material of the mother cell
Interphase- the state the cell is in when it is not dividing
Mitotic phase and cytokinesis- the process in which the end result is two genetically identical cells
Five stages of mitosis- prophase, prometaphase, metaphase, anaphase, telophase and cytokinesis
Prophase- chromatin coils up to form chromosomes, nucleoli disappear, mitotic spindle forms
Prometaphase- nuclear envelope ruptures, mitotic spindle enters the nuclear area
Metaphase- chromosomes align at midline of cell
Anaphase- sister chromatids separate and move towards opposite poles, cell elongates due to the action of non-kinetochore fibers
Telophase and cytokinesis- nuclear envelope reforms, chromosomes uncoil to form chromatin, spindle disappears, cytokinesis
Cytokinesis- cell cycle regulation
Gap 1 checkpoint- if the cell is not ready for cell division it will be stopped, if it is ready it will continue
M checkpoint- checks for full chromosomal attachment
External regulating factors- growth factor, density dependent inhibition, anchorage dependence
Internal molecule regulation- cyclically operating set of molecules that triggers and coordinates key events in the cell
Cyclin-dependent kinases- enzymes responsible for phosphorylating molecules to activate/inactivate them, present in cytoplasm
Cyclin- protein molecules whose concentration oscillates 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.
