This video shows the progression from metaphase I through anaphase I in a spermatocyte of the praying mantid Hierodula membranacea. In male meiosis I, the species has a trivalent chromosome composed of the X1, X2, and Y chromosome. Both segregation of homologous autosomes and of the trivalent can be seen in anaphase. The trivalent aligns with all of the autosomal bivalents in metaphase, and the...

In this video, we will discuss the computational approaches that enable RNA-Seq data to be efficiently mapped to an organism's genome assembly. This video, created by Dr. Le Paliulis (Bucknell University; GEP member since 2013), accompanies a presentation developed by Dr. Jeremy Buhler that provides an introduction to the core algorithms that form the basis for efficient mapping of RNA-Seq read...

This video describes how to visualize tracks available within the UCSC Genome Browser Mirror used by the GEP.
