Select ALL PARTS of Interphase.
Select the stage where DNA is synthesized (doubled).
The graph below shows the amount of genetic material present during each phase of the cell cycle.
During S phase, the cell begins making copies of all of its genetic material.
Which portion of the graph best represents S phase?
Label the diagram of the cell cycle.
The gif below shows a cell going through mitosis.
Describe mitosis.
Below is a picture of a cell. What organelle is the purple circle?
What is inside the purple circle?
The 1st phase of mitosis is prophase. Describe what is happening.
The 2nd phase of mitosis is metaphase. Describe what is happening.
The 3rd phase of mitosis is anaphase. Describe what is happening.
The 4th phase of mitosis is telophase. Describe what is happening.
Cell division ends with cytokinesis. Describe what is happening.
What are the 4 steps of mitosis in order?
Prophase
Metaphase
Anaphase
Telophase
The animation below shows two different cells.
What is the difference between Side A and Side B?
The animation below shows two different cells.
Which side divides faster?
The animation below shows two different cells.
Which side produces more cells?
Our cells make mistakes during cell replication all the time. Luckily, the G2 checkpoint catches these mistakes before those cells become cancerous. When a cell fails a checkpoint, the cell will go through apoptosis (shown in the animation below).
Based on the animation, what happens to the cell during apoptosis?
When cells lose their ability to regulate the cell cycle, they start dividing uncontrollably. This causes cancer. Cancerous cells continue to divide and can form a mass of cells called a tumor.
Question:
Which side represents cancerous cells, AND how do you know?
Support your answer with at least one piece of evidence.
Place the steps of mitosis and cytokinesis in order.
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?
The first phase of mitosis, when DNA is packed/condensed in the nucleus, is known as .
Which is the best description of metaphase?
Which is the best description of cytokinesis?
The animation above represents because .
What happens when cell division is uncontrolled?
