Asexual reproduction in one-celled organisms is considered ______ ______ (a form of mitosis).
binary fission
Cell growth
G1 (Gap 1) -
Replication DNA
S (DNA Synthesis)
Growth and preparation for mitosis
G2 (Gap 2) -
Cell division
M (mitosis)
Stops growth
G0 (G Zero)
An example of a cell that hits the G0 stage and stops growing and does not proceed in the cell cycle:
neurons
An example of a cell that hits the G0 stage and stops growing and does not proceed in the cell cycle:
Tumors
A. (Includes B, C, and D; "cell resting")
Interphase
first stage of cell cycle - cell grows
G1
DNA is copied/replicated
S
cell prepares to divide
G2
first stage of cell division
prophase
second stage of cell division
Metaphase
third stage of cell division
Anaphase
fourth stage of cell division
telophase
name for NUCLEAR division of cell division:
M
name for CYTOPLASMIC division of cell division:
Cytokinesis
Cytokinesis for PLANT CELLS - cell walls form from in to out
Cell plate formation
Cytokinesis for ANIMAL CELLS - cell membranes form from out to in
Cleavage Furrow
Chromatids of each chromosome separate at the centromere.
anaphase
Copied DNA coils into chromosomes.
Telophase
Spindle fibers disassemble (disappear).Centrosomes appear next to the disappearing nucleus.
Prophase
Kinetochore fibers move chromosomes to the cell's center.
Metaphase
A nucleus and nucleolus reform in each new cell.
Telophase
Chromatids move towards opposite poles of the dividing cell.
Anaphase
Spindle fibers radiate from the centrosomes.
Prophase
