Document Summary

Folder icon this icon represents a folder that contains various pieces of content. 1207/1208 online course, you will see a folder icon in front of each lab in the labs tab. When you select each of the lab folders, you will see the specific resources for that particular lab. Typically, these lab folders will contain your pre-lab readings in digital and pdf format, the pre-lab quizzes, the lab readings in digital and pdf format, as well as the post-lab quizzes and activities. Link icon this icon represents a link to content that is embedded in the online course or to an external website. You will see this icon used for all of the pre-lab, lab, and post-lab readings in digital format. When you select one of these links, the digital reading will appear on screen. File icon this icon represents a file that has been uploaded to the online course.

Pre Lab Questions:
1. What is the product of transcription?
2. What is the region of DNA called where transcription begins?
3. What is the product of translation?
4. In your own words define each of the following:
Silent mutation
Missense mutation
Nonsense mutation
Frame shift mutation
5. Where in the cell does translation take place?

Download and print the instructions for reference as you work through the lab. As you work through the lab fill in the table below. Use this information to answer the questions that follow contained in this document.
First read through the mutation guide. Once you close the guide you will see the buttons to begin the simulation. Note, you will be translating the mRNA strand into a protein. As you work through each of the mutations fill in the charts below. You must complete 4 mutations for this lab activity. Itâs good practice working with the codon table .
â Aris labs calls the codon table the âGenetic Code Chartâ. Use the amino acid abbreviation for the protein sequence. For example the amino acid proline is abbreviated as pro.
You have to fill in all the letters AND the resulting amino acid sequence by dragging and dropping before you click the [check] button. Abrieviate STOP as either STP or END.
For each of the three mutations you will complete, fill in the table in this lab document with the original mRNA and amino acid sequence and the mRNA sequence and the resulting amino acid sequence RESULTING FROM the mutation as outlined in the mutation rule.
The various mutations represent missense, nonsense, silent and frame shift mutations. You must complete one of each. The lab will not necessarily present the mutations in this order. You must do the mutation and identify which type it is and make sure you do one of each.
6. Frame Shift Mutation example:
Provide the mutation rule you are following.
Original A. Acids
Original mRNA
Mutated mRNA
Mutated A. Acids
7. Missense Mutation example:
Provide the mutation rule you are following.
Original A. Acids
Original mRNA
Mutated mRNA
Mutated A. Acids
8. Nonsense Mutation example:
Provide the mutation rule you are following.
Original A. Acids
Original mRNA
Mutated mRNA
Mutated A. Acids
9. Silent Mutation example:
Provide the mutation rule you are following.
Original A. Acids
Original mRNA
Mutated mRNA
Mutated A. Acids
Post Lab Questions
10. From the mutations you have explored, which one is the least severe. Explain your answer.
11. From the mutations you have explored, which one is the most severe. Why?
12. Aside from silent mutations which have no effect on amino acid sequence, are all mutations bad? Explain your answer.
