Vocabulary
The term for cells that do not undergo meiosis.
What are somatic cells?
The cell does nothing or its job in this stage.
What is G0?
This is the term for everything in the cell cycle except mitosis or meiosis.
What is interphase?
This is the phase where sister chromatids are pulled apart.
What is anaphase?
This metaphase(I or II) will line up sister chromatids instead of homologs.
What is Metaphase II?
Neighboring cells send this out to tell cells to grow.
What are growth factors?
Growth factors are this kind of molecule.
What are signaling molecules (or proteins)?
Interphase uses up a lot of this molecule.
What is ATP?
This is the phase where the chromatids align in a row.
What is metaphase?
This Anaphase(I or II) pulls homologs apart instead of sister chromatids.
What is Anaphase I?
The term for cell self-destruction.
What is apoptosis?
This is the point of no return for the cell.
What is the Restriction point?
The G1/S checkpoint checks three things.
What is everything doubled correctly, enough ATP, DNA is in good shape?
This is the phase where the nuclear envelope dissolves.
What is prophase?
This occurs right after mitosis or meiosis.
What is cytokinesis?
The name of the process of life and death of a cell.
What is the cell cycle?
The cell sends out growth factors to do this.
What is alert a neighboring cell there is room to/it is time to grow?
True or False: in S-phase, everything is doubled.
What is false, only DNA is doubled?
This is the phase where the nuclear envelope reforms.
What is telophase?
These line up in rows during meiosis I.
What are homologs?
The parts of the cell that pull the sister chromatids apart.
What are mitotic spindles (the cytoskeleton)?
Daily Double! This is what the G in G1 means.
What is Gap phase?
G-2 is the cell's last chance to do this
What is increase in size or make more organelles?
This is the order of the four stages of mitosis.
What is prophase, metaphase, anaphase, telophase?
True or false: Meiosis I has more in common with mitosis than meiosis II has in common with mitosis.
What is false?
