Mitosis and the Cell Cycle

QuestionAnswer
DNA replication produces two identical DNA molecules called_____ and it separates during mitosis sister chromatids
Region where identical DNA molecules are most tightly attached to each other centromere
Microtubules attach to chromosomes at _______ kinetochore
most of cell's growth occurs here interphase
cell structure consisting of microtubules that forms during early mitosis mitotic spindle
most of nucleus is filled with a complex of DNA and protein in a dispersed form called_____ chromatin
division of nucleus is followed by_____ in euka cytokinesis
Organizing centers for microtubules involved in separating chromosomes centrosome
(cell cycle) cell commits to go trough the cycle here G1 checkpoint
(cell cycle) DNA replication here S phase
(cell cycle) non-dividing cells exit cell cycle here G1
(cell cycle) cell divides, forming 2 daughter cells end of M phase
(cell cycle) centrosome replication G2
(cell cycle) mitotic spindle begins to form beginning of M phase
(mitosis) tubulins assemble into spindle microtubules prophase
(mitosis) microtubules attach to kinetochores prometaphase
(mitosis) cohesins join sister chromatids of duplicated chromosome prophase
(mitosis) kinetochores are motionless in relation to poles of cell metaphase
(mitosis) spindle microtubules disassemble telophase
(mitosis) kinetochores move toward poles of cell anaphase
(mitosis) cohesins break down anaphase
lengthen, shorten, disassemble? During prophase, microtubules of mitotic spindle_____ lengthen
lengthen, shorten, disassemble? During anaphase, nonkinetochore microtubules_____ and move past each other and kinetochore microtubules______ lengthen, shorten
lengthen, shorten, disassemble? during telophase, nonkinetochore microtubules_______ disassemble

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.

To see how well you know the information, try the Quiz or Test activity.
