WebMar 20, 2024 · Viruses like SARS-CoV-2 continuously evolve as changes in the genetic code (caused by genetic mutations or viral recombination) occur during replication of the genome. A lineage is a genetically closely related group of virus variants derived from a common ancestor. WebJun 10, 2024 · But sometimes mutations occur if a wrong pairing happens. If A by mistake ends up pairing with, say, C, then that will be a mutation, because it will change the coding.
