Cell Communication
How many ways do cells communicate through
3 different types
How many types of Feedback loops
2 types
What are the 3 stages of interphase
G1, S, G2
How many stages in Mitosis
5 stages
What is the most important checkpoint
G1
What are the 3 types of cell-to-cell communication called
Direct Contact, Local signaling, Long-distance signaling
What type of feedback loops are there
Positive and Negative
Longest phase of the cell cycle
Interphase
In what stage are the chromosomes pulled apart
Anaphase
What do control points do
Receive stop/go signals
Cell-to-cell communication is crucial to
the function and survival of cells
Is negative or positive feedback more common
Negative
What happens in the S stage
In what stages do the 2 daughter cells separate
Telophase and Cytokenesis
What stage do cells sometimes remain in
G0
What is Direct contact
Cell to cell communication through cell junctions
What does positive feedback do
Increases the effect of stimulus
Result of Mitosis
2 identical daughter cells
When does crossing over happen
Telophase
What does the G2 checkpoint do
Checks for completion of DNA replication and damage
What is used for long-distance signaling
Hormones
What is an effector
Muscle or gland that responds to stimulus
What is the cell cycle
The life of a cell from its formation until it divides
What are spindle fibers used for
To pull apart chromosomes
Regulation of the cell involves
Cyclins
