CC 1
When do cells copy their DNA?
S Phase (interphase)
What do the chromosomes do during metaphase?
Line up in the center of the cell (equator)
What does PMAT stand for?
Prophase, Metaphase, Anaphase, Telophase
What lines up in the middle during metaphase I? then Metaphase II?
II: Chromosome (sister chromatids)
Which phase of mitosis do chromosomes meet in the middle on spindle fibers
Metaphase
During G1 of Interphase, what is the cell doing?
Cell Grows
What are the three main parts of the cell cycle?
Interphase, Mitosis, and Cytokinesis
What is the difference between mitosis and meiosis?
Mitosis makes identical cells (2n), Meiosis creates gametes (n)
What is one reason that cells go through the process of mitosis?
To replace old cells, for growth or for repair
During the mitosis, what is the order of the phases
Prophase, metaphase, anaphase, and telophase
Give an example how our body uses mitosis.
Healing cuts, growing, nails and hair
t/f: Cells split completely in cytokinesis
True
During what phase do homologous chromosomes separate?
Anaphase I
What happens when the cell cycle becomes uncontrolled?
Cancer
Somatic cells are what kind of cells?
Body cells
t/f: Mitosis Metaphase is when homologous chromosomes split apart
False
When do the sister chromatids/chromosomes separate?
During anaphase
What is a homologous pair? (Describe where each comes from)
Sister Chromatid from Parent #1, Sister Chromatid from Parent #2, and duplicate of each
What is the difference in appearance between chromatin (interphase) and chromosomes (mitosis)?
Chromosomes = distinct X, condensed for cell division
The cell's gel-like substance is cut in half with identical organelles and DNA, and then the whole process starts over again. What phase am I?
Cytokinesis
What disappears during prophase?
The nucleus / nuclear membrane / envelope
Most of the cells in your body are made through which process?
Mitosis
What is the SUPER IMPORTANT event that happens during prophase I in meiosis?
Crossing over (synapsis)
What are the "anchors" in the cell called? (They hold one end of the spindle fibers)
Centrioles
