Cell Cycle

This unit focuses on the process of cell growth and division. Students describe the stages of the cell cycle, including the stages within interphase and mitosis. Students describe the process of DNA replication that occurs during the S stage of the cell cycle. Students describe the importance of the cell cycle to the growth of organisms and recognize that disruptions of the cell cycle lead to many types of diseases, such as cancer. Students identify the functions of different biomolecules involved in the processes investigated during this unit.

ASSIGNMENT:

1. Read through the different sections from the link above about the history of the discovery of DNA.

2. Open the "Pieces of the Puzzle" tab at the top of the screen and click on different puzzle pieces to watch short clips about how the structure of DNA was discovered.

3. Create a timeline including the contributions of: Rosalind Franklin, James Watson, Frances Crick and Edwin Chargaff.

ASSIGNMENT:

1. See me for a copy of the cell cycle foldable.

2. Watch the video on the left over the cell cycle and its phases, and place the parts of the cell cycle in the correct order. Also, label your cell cycle. This should include G1 phase, S phase, G2 phase, M phase and Cytokinesis.

3. Then, watch the video on the cell cycle and cancer.

4. One the back of your foldable, write 3-5 sentences discussing how the cell cycle is different for cancer cells than normal cells.

ASSIGNMENT:

1. See me for a copy of the data table you will need while you complete the virtual lab above. How do you think cancerous tissue will vary from normal tissue?

2. Use the instructions on the left side of the screen to complete the lab,

3. Last, answer the journal questions below your data table using COMPLETE SENTENCES.

Experimental treatment uses modified stem cells to fight cancer - CNN VideoDaniel Apodaca is a 25-year-old film student at UCLA. He's also the first patient in a clinical trial that's testing a treatment using genetically modified bone marrow stem cells to fight cancer.

ASSIGNMENT:

1) React to the video above on stem cells and cancer.

2) Write 3-5 complete sentences about your thoughts, opinions, etc.

3) Use at least one piece of evidence (such as a quote) from the text to support your statements.

ASSIGNMENT: Watch the video above on DNA structure.

1. Create a bubble map about the structure of Deoxyribonucleic Acid. You should include the terms:

nucleotide
deoxyribose
nitrogen base
phosphate
complimentary
adenine, thymine, cytosine, guanine
double helix
antiparallel

2. Then, you will assemble a paper model of DNA.

ASSIGNMENT:

1) Watch the video on DNA replication (the S phase of the cell cycle).

2) Then, complete the virtual lab/game in the link above.

3) Last, create a DNA replication comic strip, showing the steps in your comic and naming the molecules involved, including helicase, nucleotides, and DNA polymerase.

Your comic strip should include:

The process of DNA replication including the structures involved
The purpose of DNA replication
The significance of DNA replication to the organism, their ancestors, and their offspring

Done early? Make a 3-D model of deoxyribonucleic acid using materials in the drawers at the front of the room.
