1.6 Mitosis

QuestionAnswer
Prokaryotic reproduction binary fission
Eukaryotic reproduction mitosis
phases of mitosis where dyad chromosomes are seen prophase and metaphase
phases of mitosis where monad chromosomes are seen anaphase and telephase
dyad chromosome two identical sister chromatids joined together at centromere
monad chromosome sister chromatid
chromatin linear DNA wrapped around histones
phases where chromatin is seen interphase
chromosome supercoiled DNA
phases where chromosomes are seen mitosis
percentage of cell cycle spent in interphase 90%
mitosis division of the nucleus that results in two genetically identical daughter nuclei
subphases of interphase 1. G1 2. S 3. G2
4 phases of mitosis 1. prophase 2. metaphase 3. anaphase 4. telophase
Cytokinesis division of cytoplasm
Animal cytokinesis 1. contractile ring of actin and myosin forms 2. cleavage furrow near old equatorial plane
Plant cytokinesis 1. vesicles containing cellulose meet at old equatorial plate 2. forms temporary cell plate 3. forms cell wall
Formula for mitotic index number of cells in mitosis/ total number of cells
Mitotic index indicators High mitotic index: many cells are dividing (cancer) Lower mitotic index: fewer cells are dividing (controlled)
Why do eukaryotic cells use mitosis? 1. growth 2. asexual reproduction 3. tissue repair 4. embryonic development
G0 phase a resting but fully functional phase where a cell neither divides nor prepares for division
G0 phase cell examples some nerve and smooth muscle cells
Tim Hunt discovered cyclins and how they increased and decreased at different points in the cell cycle
Cyclins family of proteins that control the cell cycle by creating checkpoints
Cyclin regulation cyclins must reach a certain threshold before the cell can begin the next phase of mitosis
Cancer occurs due to uncontrolled mitosis
Process of cancer and tumors carcingens mutate to form cogenes which cause the cell to reproduce uncontrollably
Tumor abnormal mass of cells
Primary tumor original site of cancer
Secondary tumor tumor that started in another part of the body
Smoking positive correlation between smoking and cancer

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.
