| Draggable emne | arrow_right_alt | Korresponderende emne |
|---|---|---|
Synthesis "S" Phase | arrow_right_alt | The cell grows for the first time and duplicates (copies) its organelles. |
G2 Phase | arrow_right_alt | The cell duplicates (copies) its DNA. |
Mitosis "M" Phase | arrow_right_alt | The cell grows for a second time and check point. |
G1 Phase | arrow_right_alt | The nucleus divides to form two identical daughter cells. |
Label the DNA structures on the diagram below.

The amount of DNA between 5hrs-8hrs . This represents .
The amount of DNA between 8hrs-11hrs . This represents .
Match the following steps of the cell cycle to their correct definition.
| Draggable emne | arrow_right_alt | Korresponderende emne |
|---|---|---|
S Phase | arrow_right_alt | Verification of the cell contents before mitosis |
G1 | arrow_right_alt | Replication of DNA occurs |
M Phase | arrow_right_alt | Cell grows for the 1st time; organelles copied |
G2 | arrow_right_alt | Division of the nucleus into two nuclei |
Label the diagram of the cell cycle.
A student set up a table to organize the steps of the cell cycle. What should the titles of the 2 columns be? Drag one correct answer to each box. Some answers will not be used.
Once a cell has successfully gone through interphase, it will usually divide to form two _________ cells.
What is the purpose of the cell cycle?
Determine whether each step of the cell cycle belongs to Interphase or Mitosis.

Match each of the 4 steps of mitosis to its definition.
| Draggable emne | arrow_right_alt | Korresponderende emne |
|---|---|---|
Prophase | arrow_right_alt | The step of Mitosis when the chromosomes are pulled apart/away to opposite sides of the cell. |
Anaphase | arrow_right_alt | The step of Mitosis when two nuclei are formed. |
Telophase | arrow_right_alt | The step of Mitosis when the chromosomes line up in the middle of the cell. |
Metaphase | arrow_right_alt | The step of Mitosis when the chromosomes become packed/condensed and are visible. |
Match the following images to the stages of Mitosis (Not in any particular order).
Christian is observing some cells under the microscope and made the following observations:
Spindle fibers are present
Chromosomes are lined up in the center
What phase of the cell cycle is he MOST LIKELY observing?
A student observes a cell under the microscope and records their observations:
The nucleus is no longer visible.
Chromosomes (DNA) are being pulled apart by spindle fibers.
The chromosomes are going to opposite sides of the cell.
What phase of cell division is this?
A student observes a cell under the microscope and records their observations:
Two nuclei are visible and forming.
Spindle fibers are breaking down and almost gone.
The cell has not split yet.
What phase of cell division is this?
When cell reproduction occurs and is unregulated, this causes cells to grow out of control. This uncontrolled growth can produce...
Which part of the cell cycle is when mutations to DNA might occur?
Why is it important to keep the cell cycle regulated?
Many elderly people are at higher risk of developing cancer as disruptions to the cell cycle increase.
One example is an osteosarcoma, which develops in cells that create bone and then spreads rapidly to other parts of the body. This aggressive type of cancer often requires chemotherapy. In this case, an osteosarcoma could be considered a tumor.
Another example is a chondroma, which is a slow-growing mass that typically occurs on hands or feet. It can be surgically removed with minimal risk. In this case, a chondroma could be considered a tumor.
What is the role of a tumor suppressor gene?
Select THREE correct answers.
Which of the following could prevent a tumor suppressor gene from functioning properly?
Select THREE correct answers.
The amount of DNA between 11hrs-12hrs . This represents .
