Cell Cycle Basics
Interphase
Mitosis Stages
Checkpoints & Control
Cell Division & Errors
100
This is the series of events that cells go through as they grow and divide.
What is the cell cycle?
100
This is the longest part of the cell cycle, where the cell grows and carries out normal functions.
What is interphase?
100
This is the first stage of mitosis when chromosomes condense and become visible.
What is prophase?
100
These are control points in the cell cycle where the ccell checks for erros before continuing.
What are cell cycle checkpoints?
100
Mitosis produces daughter cells that are genetically like this compared to the parent cell.
What is genetically identical?
200
These are the two main overall stages of the cell cycle.
What are the interphase and the mitotic phase?
200
This interphase sub-phase is when the cell grows and makes proteins and organelles.
What is G1?
200
This mitosis stage is when chromosomes line up across the middle of the cell.
What is metaphase?
200
The checkpoint near the end of G1 checks for cell size, nutrients, and DNA damage.
What is the G1 checkpoint?
200
After mitosis, this process splits the cytoplasm and finishes cell division.
What is cytokinesis?
300
This is the phase of the cell cycle when the cell is actually dividing into two cells.
What is the mitotic phase?
300
During this interphase sub-phase, DNA is replicated.
What is the S phase?
300
During this stage, sister chromatids are pulled apart to opposite sides of the cell.
What is anaphase?
300
This checkpoint makes sure all the DNA has been copied correctly before mitosis starts.
What is the G2 checkpoint?
300
Cells that keep dividing when they're not supposed and form clumps of cells.
What are tumors?
400
During the phase, the cell grows, copies its DNA, and prepares to divide.
What is interphase?
400
In this interphase sub-phase, the cell grows and prepares for mitosis.
What is G2?
400
In this stage, nuclear envelopes reform around each set of chromosomes, which begin to uncoil.
What is telophase?
400
This checkpoint makes sure all the chromosomes are attached to spindle fibers before the cell divides.
What is the metaphase checkpoint?
400
This disease can result when cells ignore cell cycle checkpoints and divide uncontrollably.
What is cancer?
500
These are the two processes that make up the M phase.
What are mitosis and cytokinesis?
500
Name the correct order of the interphase sub-phases.
What is G1, S, G2?
500
After mitosis, this process divides the cytoplasm, forming two separate daughter cells.
What is cytokinesis?
500
Explain how cell cycle checkpoints help prevent damaged or abnormal cells from dividing.
What is they pause the cell cycle to check for DNA damage or other problems, and either repair the damage or trigger the cell to self-destruct (so the damaged cell does not divide)?
500
Explain why it is important for DNA to be copied accurately before a cell divides.
What is because mistakes in DNA replication can cause mutations that may harm the cell, cause disease, or lead to cancer?
