Investigating a Mutation in HIV-1

Students use the HIV Problem Space on the BioQuest BEDROCK Website to investigate whether a specific HIV mutation can be correlated with a decline in immune system function. In order to perform this analysis, students must generate and analyze multiple sequence alignments of HIV sequences generated from the ALIVE study.

Gene Finding in Chimpanzee

A step-by-step tutorial that takes the student through a gene identification problem in a chimpanzee BAC sequence using predictions from a gene finder (Genscan), the UCSC Browser and BLAST.

Using FlyBase RNA-Seq Tools to Investigate Gene Expression Profiles

This walkthrough illustrates how GBrowse and the RNA-Seq tools at FlyBase can be used to identify genes with similar expression patterns. This walkthrough provides an introduction to the TopoView RNA-Seq track in FlyBase GBrowse, the FlyBase Expression Profile Search tool, and the Expression Similarity Search tool. It also illustrates how the Gene2Function web site can be used to infer the function of a D. melanogaster gene based on the functions of its orthologs in other model organisms.

Chimp BAC Analysis: Genes and Pseudogene

A step-by-step tutorial that takes the student through a gene identification problem in a chimpanzee BAC sequence using predictions from a gene prediction program (Genscan), the UCSC Browser and BLAST.

Using mRNA and EST Evidence in Annotation

This exercise allows students to learn how to use mRNA and Expressed Sequence Tags (ESTs) evidence to assist their annotation efforts. An answer key is available for instructors.
