In the 1970s, researchers studying the human genome discovered that humans have viruses in their DNA. These so-called human endogenous retroviruses (HERVs) represent remnants of once-infectious viruses that became fixed in our genome. While some of them still have the potential to produce virus-like particles, HERVs have lost their ability to generate infectious virions. _______ they persist in our DNA as viral fossils that are passed on from generation to generation.Which choice completes the text with the most logical transition?
