Cell Cycle Practice Quiz

Draw an overview of the cell cycle.

Answer

What is the longest stage of the cell cycle?

Interphase answer

What is the longest stage of interphase?

G1 answer

What happens in the G1 Phase?

Growth Prepares to copy DNA answer

What happens in the S phase?

answer S stands for Synthesis DNA is copied Humans have 46 chromosomes it is doubled to 92 during the S phase answer

What happens in G2 phase?

Grows Duplicates organelles and makes proteins necessary for splitting the cell. answer

Describe the M Phase of the cell cycle.

answer M stands for mitosis, M phase is made up of four parts: Prophase Metaphase Anaphase Telophase answer

Describe prophase

answer Chromatin condenses into chromosomes The nucleus disappears The centrioles move to the sides of the cell. The spindle (microtubules) form and grab onto the DNA. answer

What happens in metaphase?

Once the microtubules pull the chromosomes to the middle it is in metaphase answer

What happens in anaphase?

The chromosomes get pulled to opposite sides of the cell. Answer

Describe telophase

answer Chromosomes are pulled to opposite sides. The nucleus reforms The cell starts to split In animals the split is called a cleavage furrow In plants the split is called a cell plate answer

Just be aware the cytokinesis is the act of splitting one cell into two cells.

Draw a cell in each phase.
