1. The road that takes us from gene to protein Anna-Rachel Gallagher Ana-Maria Dragoi James Munro Oscar Ramirez

2. Who is our lecture designed for? The class is an introductory course aimed at exposing students to a wide variety of subjects without exploring the specifics (which will be covered in higher-level courses). Our target audience is undergraduate students from different academic, cultural, racial, ethnic, and other backgrounds. The expectations are that the students read before class and come prepared to participate in class activities

3. What is the Goal? The goal is to understand the concept of gene expression and how understanding this knowledge has helped generate transgenic organisms for human use.

4. What are the Learning Objectives?: Students will learn: that proteins are generated through the processes of transcription and translation and where each of these occurs in the cell how modification of a gene can lead to a change in protein shape and/or function. components of a gene required to make a transgenic organism

5. Activity #1: Think-pair-share Answer the following question individually. Write your answers down, consider the scope of the class and the materials that have been covered. What is the main determinant of protein’s shape? Now, pair up with a person next to you and discuss your answers. If your answers are the same the group has an answer. If your answers are not the same Talk about it and write down one answer for the pair. (again, about 1 minute)

6. The Correct Answer!! The amino acid sequence of the protein is the main determinant of it’s shape. While we will acknowledge and accept that multiple factors contribute to determine a protein shape, given the level of the course we will consider this for the time being as the correct answer.

7. Activity #2 What is the correct sequence of events during gene expression? (A)Protein, transcription, DNA, translation, RNA (B)DNA, transcription, RNA, translation, protein (C)RNA, translation, DNA, transcription, protein (D)Transcription, DNA, translation, RNA, protein

8. Activity #2 What is the correct sequence of events during gene expression? (A)Protein, transcription, DNA, translation, RNA (B)DNA, transcription, RNA, translation, protein (C)RNA, translation, DNA, transcription, protein (D)Transcription, DNA, translation, RNA, protein

9. Activity #3 This is a map of a gene that has a coding region and regulatory region, working in small groups (2 to 3 people) discuss with your neighbor and fill in the blanks that describe the function of each part of the gene using the words provided in the bubble. Note there are some words that do not fit in the blanks, please choose the ones that you think are correct. For example, the regulatory region (promoter sequence) is important for where the gene is expressed and the coding sequence is important for ……………………. This exercise should take approx. 5 minutes. After the exercise is completed please write you name on the top of the handout and they will collected after class. TRANSGENE REGULATORY (promoter) Timing Amino acid sequence Protein function Expression Name: Function Amount Shape Location DNA sequence Nucleotides RNA

10. Activity #3 ANSWER SHEET. TRANSGENE REGULATORY (promoter) Amount Timing Location Amino Acid sequence Shape Protein function Expression Function Name: DNA sequence Nucleotides RNA The words left in the bubble are associated with gene expression but do not fit in the blanks.

11. Activity #4 During gene expression the messenger RNA is trafficked out of the nucleus. What happens next? (A)The ribosome translates the mRNA into protein in the cytoplasm (B)The ribosome brings the mRNA back into the nucleus to be translated (C)RNA polymerase translates the mRNA into protein in the cytoplasm (D)Nothing. That’s the end of the process.

13. Genetic engineering gene manipulation for practical purposes Activity #5 A good time to debate Sir John B. GurdonShinya Yamanaka Big discoveries: Genetic reprogramming of adult cells into STEM cells was awarded the Nobel Prize in Physiology and Medicine in 2012

14. The era of genetic engineering 2007- Induction of Stem Cells from Adult Human Cells by Defined Factors. 2013 - Hematopoietic Stem Cell Gene Therapy Benefits Genetic Diseases in Children. 1978 - Genentech announced the production of genetically engineered human insulin. 1999 - Jesse Gelsinger died due to a massive immune response following an injection with a vector carrying a corrected gene. The era of STEM cells Milestones

15. Activity #5: The great debate The students will be randomly divided into two groups (for smaller classes) and 4 or 6 groups for larger classes. This way half of the class will brainstorm about the positive side and advantages of using genetic engineering (in medicine, agriculture etc) while the other group will think about possible negative effects. Students will have 10 minutes to think about and write down a list of possible pros/cons of genetic engineering. After the exercise is completed students will write down their ideas on the board. Discussion will start once all the groups have written down their ideas and the students can defend their points of view.

17. We hope we accomplished our goals At the end of our lecture we hope that the students have an understanding of: 1.How proteins are made and where this occurs in the cell. 2.How modification of a gene can lead to a change in shape and and/or function. 3.How our understanding of these concepts has led to the design and use of transgenic animals for human benefit.
