WebJul 4, 2011 · Abstract. Recombination occurs in many RNA viruses and can be of major evolutionary significance. However, rates of recombination vary dramatically among RNA viruses, which can range from clonal to highly recombinogenic. Here, we review the factors that might explain this variation in recombination frequency and show that there is little ... WebBecause influenza virus genomes are formed by 8 separate pieces of RNA (called “genome segments”), sometimes these viruses can “mate,” in a process called, “reassortment.” During reassortment, two influenza viruses’ genome segments can combine to make a new strain of influenza virus.

Viruses "commandeer" the host cell and use its resources to make more viruses, basically reprogramming it to become a virus factory.

Shift can happen in several ways: when a flu strain jumps to a species which it has never before infected, or when the process of viral reproduction creates a novel strain. In either case, the human immune system perceives the strain as unfamiliar. philosophy\\u0027s 10
