Gene Annotation

Module 5. Translation: The need for an Open Reading Frame

In this module students will learn how mRNA is translated into a string of amino acids. After completing this module students will be able to determine the codons for specific amino acids as well as start and stop codons. They will be able to identify open reading frames for a given gene, define the phases of splice donor and acceptor sites and describe how they impact the maintenance of the open reading frame.

Module 3. Transcription, Part II: What happens to the initial transcript made by RNA pol II?

This module demonstrates how the transcript generated by RNA polymerase II (the pre-mRNA) is processed to become mature mRNA using the sequence signals identified in Module 2. After completing this module students will be able to use the genome browser to explain the relationships among pre-mRNA, 5′ capping, 3′ polyadenylation, splicing, and mRNA.

Module 2. Transcription, Part I: From DNA sequence to transcription unit

This module illustrates how a primary transcript (pre-mRNA) is synthesized using a DNA molecule as the template. After completing this module students will be able to explain the importance of the 5′ and 3′ regions of the gene for initiation and termination of transcription by RNA polymerase II, and identify the beginning and end of a transcript using the capabilities of the genome browser (RNA-Seq, Short Match).

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.

Web Databases for Drosophila

This PowerPoint presentation introduces the species-specific databases available on the web, including FlyBase and the Ensembl Drosophila melanogaster database.
