Mitosis and Meiosis

TermDefinition
G1 Growth, making of new proteins and organelles are synthesized.
S Chromosomes replicated and DNA made.
G2 Organelles and molecules for cell division made.
Diploid Cell that contains 2 sets of chromosomes.(2N)
Haploid Cell that contains one set of chromosomes (N)
Homologous pair A pair of chromosomes where one comes from each parent.
Tetrad Structure containing 4 chromatids.
Crossing over Process in which homologous chromosomes exchange portions of chromatids.
Meiosis Process that creates gametes by separating two the sets of genes... each gamete has one set (haploid)
Metaphase I Tetrads line up at the equator, spindle fibers attach to centromeres of tetrad
Telophase II/cytokinesis Daughter cells divide forming 4 haploid cells.
Prophase I Synapsis occurs, crossing over occurs, centrioles move to opposite poles.
Anaphase II Sister chromatids separate
Anaphase I Homologous pairs separate.
Telophase I/ cytokinesis Two daughter cells are created
Metaphase II Chromosomes line up along the equator, not in homologous pairs.
Gene An area on a chromosome that codes for a specific trait.
Chromosome Is made of DNA, it is condensed genetic material.
Interphase Cell grows and replicates its DNA and Centrioles. Genetic material in form of chromatin.
Prophase Chromosomes are visible, each chromosome consists of two chromatids.
Metaphase Chromosome line up at the center of the cell.
Anaphase Sister chromatids separates into individual chromosomes
Telophase Nuclear envelope reforms and two daughter cells form.
Centromere Each pair of chromatids is attached in this area.
Cytokinesis Division of the cytoplasm
Interphase The "in-between" period of cell growth
Cell Cycle Series of events that cells go through as they grow and divide
Cancer Disorder in which some of the body's own cells lose the ability to control growth.
Polar Bodies Cells produced in females that do not participate in reproduction.

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.
