Prior Knowledge:
SWBAT transcribe and translate a gene, and describe the effects of mutations on this gene.
Lesson Objective:
SWBAT analyze the effect of a DNA mutation in the MLH1 gene on the susceptibility of a patient for colon cancer.
Lesson Assessment:
Performance assessment
Benchmark or Standards:
B.1.7 Explain that complex interactions among the different kinds of molecules in the cell cause distinct cycles of activities, such as growth and division. Note that cell behavior can also be affected by molecules from other parts of the organism, such as hormones.
B.1.8 Explain that cellular differentiation results from gene expression and/or environmental influence.
B.1.25 Explain that gene mutation in a cell can result in uncontrolled cell division, called cancer. Also know that exposure of cells to certain chemicals and radiation increases mutations and thus increases the chance of cancer.

Materials Needed:
Guided reading questions, computers, internet access, graphic organizer
Procedures:
| Time | Learning Task | Method or Procedure |
|---|---|---|
| 3 | BW: Recall our work last unit with cancer. What is cancer? How does it affect the cell cycle? What were some of the genes that were involved? | Bellwork |
| 2 | Prayer | |
| 45 | Intro to MLH1 and HNPCC: define tumor-suppressor and oncogenes, mismatch repair proteins, the MLH1 gene and what it codes for, what is HNPCC, how people are diagnosed with HNPCC, the genes thought to be involved with HNPCC, the potential relationship between HNPCC and MLH1, etc | Pair work on guided reading and questions, Lecture for supplementary material not in the reading |
| 4 | What is our goal for this experiment? To determine the extent to which mutations in the MLH1 gene may cause cancer. | Notes and questioning |
| Day 2 | ||
| 2 | Prayer | |
| 50 | Students will go to the computer lab and use on-line transcription and translation tools to determine the exact DNA and any subsequent amino acid mutations for patients with HNPCC. The students are given the DNA sequence in a file, and they must analyze the sequence using the on-line tools. | Computer lab |
| Day 3 | ||
| 2 | Prayer | |
| 10 | Summarize the results. Each group reveals the mutation of their patient (both the DNA and any subsequent AA mutations), and students fill out a chart showing the results. | Graphic organizer |
| 5 | Results Analysis. Students will begin to draw conclusions based off of these results | Pair work |
| 10 | Results Analysis. Students will begin to draw conclusions based off of these results | Class Discussion |
| 10 | Description of the paper requirements | Lecture with Handout |
| 20 | Work on independent paper | Computer Lab |
Changes for Next Time:
Here the lesson author can reflect on changes for future years. After executing the lesson in the classroom, the member can edit this section of the wiki resource to describe changes for making the lesson more effective next time
What Worked Well:
After executing the lesson in the classroom, edit the wiki resource to highlight particularly effective activities or assessments for reference in future years.
