Chemistry

TermDefinition
Mitosis -----Process by which the hereditary material in the parent CELL replicates and divides into two (2) IDENTICAL daughter nuclei (cells).
Diploid (number) the total number of chromosomes in normal body cells; two matching homologs of each kind
Chromosome(s) a threadlike body in the cell nucleus that carries the genes in a linear order
Interphase Interphase ‘RESTING PHASE’ which occurs between mitotic cycles. The cell grows and replicates here.
Crossing over the interchange of sections between pairing homologous chromosomes during the prophase of meiosis
Anaphase chromosomes move to OPPOSITE poles
Haploid/Monoploid hapliod (of a cell or nucleus) having a single set of unpaired chromosomes. monoploid having the basic or haploid number of chromosomes.
Daughter nuclei daughter nuclei The nuclei that result from the division of a single nucleus.
Tetrad A four-part structure that forms during the prophase of meiosis and consists of two homologous chromosomes, each composed of two sister chromatids.
Gametogenesis Gametogenesis( production of the games)
Meiosis (genetics) cell division that produces reproductive cells in sexually reproducing organisms
Metaphase the second stage of mitosis
Cytokinesis ----The cell membrane pinches in and the CYTOPLASM divides into two (2).
Disjunction disjunction happens when homologous chromosomes move apart toward the opposite poles of the cell in anaphase I.
Variation Variation happen during Crossing over in prophase I
Replication The process when the DNA makes a copy of itself before cell division
Synapsis the side by side pairing of homologous maternal and paternal chromosomes at the start of meiosis
Prophase Prophase first phase, double chromosomes are VISIBLE
Centrioles one of two tiny structures located in the cytoplasm of animal cells near the nuclear envelope

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.
