Cell Cycle/Interphase
What is the Cell Cycle?
•The cell cycle is the ordered series of events a cell goes through to grow and divide into two identical daughter cells
What happens to the cell if it doenst pass the checkpoint?
if the cell does not pass the G1 checkpoint, it may pause to repair any damage or enter a non-dividing state called the G0 phase. This means the cell dies.
T or F? The S phase is the second phase?
True. The S phase is the second phase of interphase, which comes after the G1 phase and before the G2 phase.
T or F? The S phase is the 3rd phase of the cell cycle?
True.
What is prophase?
Prophase is the first phase of mitosis, this is the process that separates the duplicated genetic material in the nucleus of a parent cell into two of the same daughter cells.
How much time in a cells life does it spend in interphase?
90%
What happens at the G1/S checkpoint?
This checkpoint, also known as the "restriction point," is a critical control point that determines whether the cell is ready to commit to DNA replication.
When the DNA is copied, what happens?
Each chromosome is duplicated into two identical sister chromatids.
What is cell growth?
The cell continues to grow and increases its cytoplasmic content.
What is metaphase?
Metaphase is the stage during theprocess of cell division mitosis ormeiosis. Normally, singularchromosomes are spread out in thecell nucleus. During metaphase,the nucleus dissolves.
How many daughter cells are created through the cell cycle?
2 identical daughter cells
The Gap 1 phase is the shortest. True or False?
False. The G1 phase is the longest phase.
When does this phase occur?
This phase occurs between the G1 phase and the G2 phase.
What happens at the checkpoint?
The cell undergoes a checkpoint to ensure that DNA replication is complete and that all structures are ready before proceeding to mitosis.
What is anaphase?
Anaphase is the stage of the cell cycle which duplicated chromosomes split and move towards opposite poles of the cell.
What is interphase?
•Interphase is the phase in which a cell spends 90% of its life in. Interphase is what they call the "daily living. in which the cell obtains nutrients and grows, as well as replicates its DNA in preparation for mitosis
What happens in the Gap 1 phase?
Cells grow, carry out and replicate their organelles.
How many chromosomes do you end with?
46 chromosomes.
What does the cell check for?
The cell checks for and repairs any DNA damage from the S phase to maintain genetic stability.
What is cytokinesis?
Cytokinesis is the physical process of cell division, in which it divides the cytoplasm of a parent cell into two daughter cells.
How many stages are in the cell cycle?
Four. G1, S, G2, and M
What is the G1 phase?
This is the phase where the cell grows and becomes pervasive in size and synthesizes mRNA, and proteins that are required for DNA synthesis. Once they require the proteins, the growth is complete.
What is the main thing that happens during S phase?
The DNA within the nucleus is copied.
What happens in the G2 phase?
In the G2 phase, the cell continues to grow and prepares for mitosis by synthesizing proteins, making more organelles, and repairing any DNA damage that occurred during the previous S phase
What is telophase?
Telophase is the last and final phase of mitosis, this is the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells.
