However, very little is known about RNA viruses in an environmental context, and even less is known about their diversity and ecology in soil, 1 of the most complex microbial systems. WebDec 24, 2024 · Different types of virus have varying sites of synthesis and replication. For example, synthesis and replication for DNA viruses occur in the cell’s nucleus while it is usually the cytoplasm for RNA viruses. Virus assembly depends on the site of synthesis and such sites are the nucleus, endoplasmic reticulum, and the Golgi apparatus aka Golgi ...
WebMar 25, 2024 · RNA viruses have small genomes which are subject to constant change. These changes, called mutations, help the virus adapt to and infect new host species. It is thought that the new COVID-19 likely originated from bats but it is not yet known whether mutations allowed this jump from animals to humans.
