This module explores how multiple different mRNAs and polypeptides can be encoded by the same gene. After completing this module students will be able to explain how alternative splicing of a gene can lead to different mRNAs and illustrate how alternative splicing can lead to the production of different polypeptides and result in drastic changes in phenotype.
This module uses mRNA data to identify splice sites. After completing this module students will be able to identify intron-exon boundaries using canonical splice donor and acceptor sequences and determine which are best supported by RNA-Seq and TopHat splice junction predictions.
