The first gap, or growth phase, of the cell cycle, consisting of the portion of interphase before DNA
synthesis begins.
S phase
The synthesis phase of the cell cycle; the portion of interphase during which DNA is replicated.
G2 phase
The second growth phase of the cell cycle, consisting of the portion of interphase after DNA synthesis
occurs.
Mitosis
part of eukaryotic cell division during which the cell nucleus divides
-prophase, metaphase, anaphase, telophase
prophase
Chromosomes become visable, nuclear envelop dissolves, spindle forms
Metaphase
Chromosomes line up in the middle of the cell
, anaphase
Phase of mitosis in which the chromosomes separate and move to opposite ends of the cell
telophase
After the chromosome seperates, the cell seals off, Final Phase of Mitosis.
Cytokinesis
division of the cytoplasm to form two separate daughter cells
G0 phase
A nondividing state occupied by cells that have left the cell cycle, sometimes reversibly.
cell cycle check points
control mechanisms in eukaryotic cells which ensure proper division of the cell
G1, S, G2, M
G1 checkpoint
checks for cell size, nutrients, growth factors and DNA damage
S checkpoint
