Check points/communication
This checkpoint checks to make sure that DNA has been replicated properly.
G2
Regulatory proteins in the cell cycle
cyclins and CDKs
Hormones and pheromones use what type of cellular communication?
endocrine
binary fission
When cells can no longer be regulated by the cell cycle, they are considered what?
CANCEROUS
Metaphase plate
Before a cell can enter mitosis, it must spend a large majority of its life in what phase?
interphase
The nervous system uses this receptor to move electrical (charged molecule) messages through the body.
ligand-gated ion channels
daughter cells
Cancer cells can move throughout the body to form new tumors. The lack of what allows this?
anchorage dependence
Phosphorylation happens by proteins known as __________.
kinase
This triggers a cell's movement from G2 phase to M phase
maturation promoting factor
The signal transduction pathway must first start with signal molecules. What do we call these?
ligands
Uncondensed DNA that is expressed is called
Euchromatin
This process describes what happens when a cancer or tumor spreads through the body.
metastasize
Type of receptor that binds to GDP/GTP
G-protein coupled receptors
s phase
Uses a special dimer to induce a signaling cascade
tyrosine kinase receptor
What type of cells must go through one cellular division in order to produce diploid cells?
somatic body cells
These special proteases initiate apoptosis
caspases
The endocrine system sends out hormones which travel
long distance, through the bloodstream
Total number of sister chromatids in a human gamete at the end of prophase 1
92
Cyclic AMP is an example of this type of molecule that allows for responses to be amplified.
secondary messenger
microtubules attach to these proteins to help move chromosomes during cell division
kinetochores
Conifers and angiosperms (flowering plants) do not have this particular mechanism in cell division
Centrioles/Centrosome
