100
The first stage of the cell cycle
What is interphase
100
The primary checkpoint in the G1 phase that determines whether a cell will proceed to S phase, delay its division, or enter G0 phase?
What is the G1 checkpoint?
100
1 is pointing to:
What is Centrosomes?
100
The process by which a cell makes an identical copy of its DNA, occurring during the S phase of interphase.
What is DNA Replication?
100
The first phase of interphase
What is G1 Phase (cell growth)?
200
This preparatory phase ensures that the cell is the right size, its organelles are functioning correctly, and its genetic material is duplicated before entering the division phase (mitosis or meiosis).
What is interphase?
200
In which phase of the cell cycle does DNA replication occur, resulting in two identical copies of each chromosome?
What is the S phase?
200
2 is pointing to:
What is Plasma Membrane?
200
Two identical copies of a chromosome produced during DNA replication and held together by a centromere. They separate during cell division.
What is Sister Chromatids?
200
The second phase of interphase
What is S phase (DNA synthesis)?
300
G0, G1, S, and G2
What are the phases of interphase?
300
Which phase of the cell cycle immediately follows the S phase and is characterized by further growth and preparation for cell division?
What is the G2 phase?
300
3 is pointing to:
What is Nucleolus?
300
A specialized region of a chromosome that holds sister chromatids together and is important for their proper segregation during cell division.
What is Centromere
300
The third phase of interphase
What is G2 phase (cell growth)?
400
The DNA replicates and the cell gets ready for division.
What is the primary purpose of interphase in the cell cycle?
400
What is the name of the protein complex that checks for DNA damage and ensures DNA replication has occurred correctly during the G2 phase?
What is the G2 checkpoint?
400
4 is pointing to:
What is Nuclear Envelope?
400
A single, duplicated strand of a chromosome.
What is Chromatid?
400
The percent of the cell cycle that interphase accounts for
What is 90%?
500
Interphase is followed by which major event in the cell cycle?
What is mitosis or meiosis
500
Cells that are temporarily or permanently not actively dividing enter which non-dividing phase of the cell cycle?
What is the G0 phase?
500
5 is pointing to:
What is Chromatin?
500
The complex of DNA and proteins in a cell's nucleus, involved in gene regulation and structure.
What is Chromatin?
500
One cell throughout the entire process
What is the amount of cells at the beginning to the end of interphase?
