In a well-known example of a satellite-helper system, Hepatitis D virus requires the presence of its helper Hepatitis B virus to make copies …
Most people associate viruses with illness and suffering, however, considering that the vast majority of viruses cause no illness and are actually beneficial to humans and the planet as a whole, this sentiment is largely misplaced.
Viperin is a conserved antiviral protein that catalyzes the synthesis of chain terminator molecules in both vertebrates and prokaryotes.
