Biology B: Cell Cycle and Steps of Mitosis

Multiple Choice

During which phase of the cell cycle does the cell spend the most time?

• Mitosis

• Cytokinesis

• Interphase

Labelling

Click where DNA replication takes place

Match

Match each phase with its correct description

• Cell grows rapidly while carrying out normal functions.

• Cells must replicate their DNA before cell division to ensure that identical genetic information is passed to  the next generation.

• FINISHES GROWING,

  Errors in DNA replication are checked- if something is wrong, cell needs to fix its errors before it divides!

Multiple Choice

In anaphase, how are the chromosomes pulled apart?

• They diffuse to opposite sides of the cell.

• They are pulled by shortening spindle fibers.

• They are attracted by the centriole like magnets.

• They are transported by proteins.
