Annotation of Drosophila
This PowerPoint presentation describes the recommended annotation strategy for Drosophila projects. The presentation provides an overview of the goals of the GEP annotation project, an introduction to NCBI BLAST, web databases, and the issue of reading frames and phase.
Simple Annotation Problem
This worksheet will guide you through a series of basic steps that have been found to work well for annotation of species closely related to Drosophila melanogaster. It provides a technique that can also be the foundation of annotation in other, more divergent species but in those cases other special techniques will probably be needed.
Annotation of a Drosophila Gene
This walkthrough uses the annotation of a gene on the D. biarmipes Muller F element to illustrate the GEP comparative annotation strategy. This document shows how you can investigate a feature in an annotation project using FlyBase, the Gene Record Finder, and the gene prediction and RNA-Seq evidence tracks on the GEP UCSC Genome Browser. The walkthrough then shows how you can identify the coordinates of each coding exon using NCBI BLAST, and also includes a discussion on the phases of the donor and acceptor splice sites. The walkthrough concludes by verifying the proposed gene model using the Gene Model Checker; it also includes a sample GEP Annotation Report.
Annotation of Drosophila Primer
This PowerPoint presentation provides a brief primer on the recommended annotation strategy for Drosophila projects. The presentation provides an overview of the goals of the GEP annotation project, an introduction to RNA-Seq, web databases, and a discussion on the phases of the splice donor and acceptor sites.
Finding Genes in a New Fly Genome
This exercise was developed by Dr. Anya Goodman (California Polytechnic State University) and Dr. James Youngblom (California State University, Stanislaus). This exercise engages students in annotating genomic DNA from less famous species of Drosophila while teaching basic bioinformatics skills.
A Simple Annotation Exercise
Dr. Justin R. DiAngelo (Penn State Berks) has developed an exercise that takes students through a series of steps to annotate a gene in a Drosophila biarmipes contig. Students will construct a gene model using gene predictions, BLASTX searches, and the GEP UCSC Genome Browser mirror. Students will then verify their final gene model using the Gene Model Checker.
