Description
This module contains activities to help students understand the biology of programmed translational frameshifts (PTFs) in phages, how to identify PTFs, and how to annotate them.
Learning objectives:
After completing this module, students should be able to:
- Annotate a programmed translational frameshift
- SEA-PHAGES Bioinformatics Guide: What is a programmed translational frameshift? (https://seaphagesbioinformatics.helpdocsonline.com/article-6)
- Videos on annotating frameshifts in DNA Master
- Video on annotating a frameshift in PECAAN
- PECAAN_frameshiftcoding.mp4 (Video File included in this set of teaching resources)
- Identify the protein products of the FS and the function of the protein products (see “Programmed Translational Frameshifts Powerpoint”)
- Explain how the ribosome produces protein products from the FS (see “Programmed Translational Frameshifts Powerpoint”)
- Explain/present the data on PTFS from journal articles in the primary literature (see “Guidelines_for_Journal_Club_Presentation--Students.docx, ”Guidelines_for_Journal_Club_Presentation_WithExample--for_Faculty_with_Assessment.docx" and Frameshift Articles)
How is the module structured to promote student development as a scientist? Students using activities in this module will use primary literature, find and annotate a PTF, and work with other student scientists.
