Bio notes cell division

TermDefinition
s phase the part of a cell cycle (during interphase) in which the cell undergoes DNA Replication
interphase The portion of the cells life in which normal cell activities occur and the cell spends most of its life here.
M Phase The part of the cell cycle in which the cell divides (contains mitosis and cytokinesis).
Cell Cycle a diagram that identifies the stages of a cell.
Anaphase The 3rd stage of the nuclear division in which the chromosomes are pulled away from each other by the centrioles tugging on the spindle fibers.
Chromosome A highly condensed strand of DNA wrapped up with proteins-only visible in the M phase-Humans have 46(2 pairs of 23).
G Phase the part of the cell cycle during the G1 Phase in which a major checkpoint prevents the cell from undergoing cell division.
Sister chromatid 2 identical copies of a chromosome-generally shows connected by their centromere to form an X shape.
homologous 2 versions of the same chromosome. For example, Chromosome 3 from mother and chromosome 3 from father have the same type of genetic information, but may have different variations of the gene.
daughter cell the product of cell divisions. Mitosis produces two identical daughter cells and meiosis produces 4 unique daughter cells with only 1/2 the DNA from the original cell.
haploid A cell that has only 1 copy of each chromosome, shown as an n, which is only 1/2 the DNA from the original cell.
prophase The first step in nuclear division in which the chromatin condenses into chromosomes and the nuclear envelope begins to disappear.
mitosis The division of the nucleus; a form of asexual reproduction in some eukaryotic cells including animals.
meiosis a form of nuclear division that leads to the haploid cells preparation for sexual reproduction.
checkpoint A series of proteins that are responsible for ensuring that specific milestones have been met prior to allowing the cell cycles/cell division to occur.
metaphase the second stage of nuclear division in which the chromosomes line up at the equator of the cell attached by their centromeres to the spindle fibers.
telophase the final stage of nuclear division in which the chromosomes are completely separated from each other and a new nuclear envelope will eventually form.
G1 the part of the cell cycle in which the cell is undergoing normal cell growth and processes.
cytokinesis the division of the cytoplasm(everything outside the nucleus).
G2 the part of the cell cycle(during interphase) in which the cell prepares for division by making extra copies of organelles.

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.
