Cell Cycle Flashcards
The _____is regulated series of events in a cells life that involves cell growth DNA replication and cell division
The _____ is crucial for cell growth,repair, and reproduction
Cell cycle
It involves the distribution of identical genetic material or DNA to 2 daughter cells
Cell division
Events: During the ___phase the cell grows in size, carries out its normal functions and prepares for DNA replication
Purpose: to ensure the cell is ready for DNA synthesis and subsequent cell division
Duration: 11hrs
G1 phase
Events: DNA replication takes place.The cell’s entire genome is duplicated, resulting in the formation of two complete sets of chromosomes,
Purpose: To accurately duplicate the genetic material to ensure that both daughter cells receive
identical copies during cell division
Duration: 8 hours
S phase
Events:The cell continues to grow synthesizes proteins, and prepares for cell division. It also checks for DNA replication errors and monitors the cell’s overall readiness for division
Purpose: serves as a checkpoint to ensure that DNA replication has occurred correctly and thatvthe cell is on optimal condition for mitosis or meiosis
Duration: 4hrs
G2 phase
Events: The actual cell division phase. in mitosis, the cell division takes place in body cells. In meiosis cell division happens in germ cells
Purpose: To distribute the duplicated genetic material and cellular organelles into daughter cells, ensuring their proper formation.
Duration: 1 hour
M phase
Events: The actual cell division phase. in mitosis, the cell division takes place in body cells. In meiosis cell division happens in germ cells
Purpose: To distribute the duplicated genetic material and cellular organelles into daughter cells, ensuring their proper formation.
Duration: 1 hour
M phase
Some cells. after completing the ___phase, may enter a non-dividing state called the ___phase. Cells in Go are temporarily or permanently withdrawn from the cell cycle.
•Lack of essential nutrients or growth factors.
•When subjected to stress or damage, enter ___temporarily until conditions become favorable for cell division again.
GO phase
Critical for maintaining the fidelity of the cell cycle and preventing the propagation of damaged or
genetically unstable cells.
