phases
sister chromatids are moving apart
Anaphase
often secreted from the cell and released into the extracellular space
Sending cell
complex signaling pathway inside of a cell begins with a single key event
binding of a signaling molecule, or ligand, to its receiving molecule, or receptor
What occurrence within the cell does the cell cycle represent?
Cell division
How many phases make up mitosis?
4
nucleolus begins to fade from view
Prophase
general term for molecules that bind specifically to other molecules
ligands
found inside of the cell (in the cytoplasm or nucleus)
intracellular receptors
What is the longest phase in the cell cycle?
Interphase
True or False: Cytokinesis is included in the phases of mitosis
False
new nuclear membrane is forming around the chromosomes.
Telophase
junction between two nerve cells where signal transmission occurs
synapse
found in the plasma membrane
cell surface receptors
The cell cycle results in two genetically _________ cells.
Identical
True or False: Interphase is not included in the phases of mitosis.
True
a chromosome pair connected by a centromere, what is each individual chromosome called?
Chromatid
promotes growth, particularly of the skeleton and cartilage
growth hormone
are ion channels that can open in response to the binding of a ligand
Ligand-gated ion channels
The cell cycle state where the cell grows to its full size, copies the DNA and organelles and prepares to divide is called the ________________.
Interphase
What type of reproduction is occurring during mitosis?
Asexual
During what phase of mitosis do centromeres divide and the chromosomes move toward their respective poles?
Anaphase
to diffuse between the two cells
intracellular mediators
are a large family of cell surface receptors that share a common structure and method of signaling
G protein-coupled receptors (GPCRs)
What is the importance of the cell cycle to multicellular organisms with respect to tissue repair?
The cell cycle replaces damaged, worn, and aging cells
List the phases of mitosis in order.
