Cell Cycle Exam

Mason was observing a small cut on his hand heal over time. Anika explained that this was due to a certain process. What is the purpose of this process, also known as mitosis?

• To increase the surface area of Mason's cell

• To allow Mason's cells to divide for growth, repair, and renewal of the cut

• For increasing genetic variation within Mason

• To allow for DNA replication and protein synthesis in Mason's cells

Mia, Anika, and Aria are studying biology. They learned that mitosis results in the formation of...

• Two identical cells with all of the original chromosomes

• Two different cells with half of the original chromosomes

• Four identical cells with all of the original chromosomes

• Four different cells with half of the original chromosomes

Daniel, Harper, and Noah are studying biology together. They are trying to remember the correct order of the stages of the cell cycle. They came up with the following order: G2, S, G1, M.  Can you help them put these stages in the correct order?

• G1, S, G2, M

• S, G1, G2, M

• G1, M, G2, S

• M, G1, S, G2

In a biology class, Ava and Mia were studying about the cell cycle. They learned that during the "s" phase of the cell cycle, DNA is duplicated. Rohan, their classmate, asked why this is important. What could be the correct explanation?

• It allows for each daughter cell to be genetically DIFFERENT, just like Ava and Mia are different from each other.

• It allows for each daughter cell to be genetically IDENTICAL, just like how Rohan's identical twins would be.

• It allows for each daughter cell to have 2X the amount of DNA as the parent cell, like doubling the number of biology textbooks.

• It allows for each daughter cell to have half the amount of DNA as the parent cell, like splitting a pizza into two equal halves.

During a biology class, Aria, Henry, and Elijah were studying the cell cycle. They were asked to identify the longest stage of the cell cycle, which is also the stage where the cell spends most of its life. What is this stage called?

• Cytokinesis

• M phase

• Interphase

• G1 Phase

Abigail is studying the stages of cell division under a microscope. She identifies a stage where the chromosomes condense and become visible. What stage is this likely to be?

• Prophase

• Metaphase

• Anaphase

• Telophase

During a biology class experiment, Benjamin, Isla, and Avery observed a cell under a microscope. They noticed a particular phase where each DNA gets pulled to the opposite sides of the cell. What phase were they observing?

• They were observing a phase where DNA lines up in the middle of the cell and DNA attaches to spindle fibers

• They were observing a phase where centrioles and spindle fibers appear

• They were observing anaphase

• They were observing a phase where DNA gets copied
