Now, coronavirus has different mutations, strains and variants, which may have some people muddled.
Viruses have to establish a stronghold in a host’s cells to take biological material, which it uses to replicate.
Replication allows the virus to spread through the body, and sometimes results in “errors” according to Lara Herrero and Eugene Medzokere, researchers at Griffith University.
Replicated errors are, in fact, mutations, which cause inexact copies of the virus known as variants, they wrote for The Conversation.
