Part 1: Introduction
Reassortment is the exchange of entire RNA segments, also called subunits, between genetically related viruses. This animation depicts a single human cell infected concurrently with two strains of influenza virus. Once inside the cell the eight RNA subunits of each virus replicate to produce additional RNA subunits. Different combinations of the RNA segments generated from each parental virus are incorporated into progeny viruses. Click on "Play" to start the animation.
