Interphase
"Interphase is the longest phase of the cell cycle."
True or false
True
Interphase is indeed the longest phase of the cell cycle.
At what stage do chromosomes align in the center of the cell?
In the stage Metaphase.
Is cytokinesis the final stage of the cell cycle?
Yes, cytokinesis is the final stage of the cell cycle that ensures cell division.
What process involves the division of the cytoplasm to form two separate daughter cells after nuclear division (mitosis)?
A. Prophase
B. Metaphase
C. Cytokinesis
D. Telophase
C. Cytokinesis
Which phase of the cell cycle is generally the shortest?
Cytokinesis
Which checkpoint ensures the cell is ready for DNA synthesis?
The G1 checkpoint makes sure the cell is ready for the S phase by making sure the cell has a sufficient cell size.
What is the order of the stages of Mitosis in the cell cycle?
(Prophase, Metaphase, Anaphase, Telophase)
Also known as (PMAT)
When does cytokinesis occur in the cell cycle?
It occurs right after mitosis (generally Telophase).
What structure attaches one sister chromatid to another?
A. Centromere
B. Chromatin
C. Centrosome
D. Spindle Fibers
A. Centromere
Which phase of the cell cycle occupies the majority of a cell's life, during which it grows and replicates its DNA?
Interphase
What are the 3 stages of Interphase?
G1 Phase
S Phase
G2 Phase
What is the primary purpose of mitosis?
To produce two genetically identical daughter cells for the purpose of growth and repair.
How many daughter cells are typically created from one parent cell following mitosis and cytokinesis?
Two daughter cells
What is the correct order of the phases in the cell cycle?
A. G1, G2, S, M
B. S, M, G1, G2
C. G1, S, G2, M
D. M, S, G1, G2
C. G1, S, G2, M
What is the cell cycle?
The cell cycle is a series of events in which a cell goes through in order to grow and divide.
Approximately how long is the cell cycle spent in interphase?
About 90% of the cell cycle is spent in interphase.
What is the result of uncontrolled mitosis?
Cancer
What happens if a cell completes mitosis but fails to undergo cytokinesis?
If this happens, it will result in a cell that contains more than one nucleus.
During which specific phase of mitosis does the sister chromatids separate and move to opposite poles of the cell?
A. Prophase
B. Telophase
C. Metaphase
D. Anaphase
D. Anaphase
What is the main difference of cytokinesis between animal cells compared to plant cells?
Plant cells form a cell plate to divide, while animal cells undergo cleavage. (Pinching of the cell membrane)
Which organelle, crucial for organizing spindle fibers, replicates during interphase?
The centrosome.
If a cell has 20 chromosomes, how many chromatids are present during the phase metaphase?
40 Chromatids (Each chromosome has two sister chromatids)
What is the definition of cytokinesis in the context of the cell cycle?
The division of the cytoplasm into two daughter cells.
Which checkpoint ensures that DNA replication is complete and accurate before the cell enters mitosis?
A. G1 checkpoint
B. G2 checkpoint
C. M (Metaphase) checkpoint
D. G0 checkpoint
B. G2 checkpoint
What is the G0 phase in interphase?
A non-proliferative state where the cell exits the active cell cycle.
