What is the result of the cell cycle?

• Three cells

• Four daughter cells

• Two identical daughter cells

• One clone cell

Match each phase with its correct description

• G1 Phase

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

• G2 Phase

• Cell grows rapidly while carrying out normal functions.

• S Phase

• • FINISHES GROWING

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

Put the following actions in order: DNA replicates, cell grows, cell divides, cell prepares for mitosis. 

• DNA replicates, cell grows, cell prepares for mitosis, cell divides
• cell grows, cell prepares for mitosis, DNA replicates, cell divides
• cell grows, DNA replicates, cell prepares for mitosis, cell divides
• DNA replicates, cell prepares for mitosis, cell grows, cell divides

What does DNA Replication mean?

• DNA is made.
• DNA makes new cells. 
• DNA copies itself.
• DNA starts the cell cycle.

Why would it be important to replicate DNA before a cell divides in mitosis or meiosis?

• In order for genetic information to be transferred into daughter cells.
• In order for the cell to be able to increase in size.
• In order for the DNA to be contained in the nucleus.
• In order for the cell to re-order the DNA sequencing in the new cells.

Match the following

• Telophase: Chromosomes are pulled to opposite end and two nuclei form.

• 
• Interphase: Resting phase between mitosis cycles.

• 
• Anaphase: Chromosomes are pulled apart.

• 
• Metaphase: Chromosomes align in the middle.

• 
• Prophase: Chromatin condenses.
