by Gertrud U. Rey Errors during viral replication can give rise to shortened and/or rearranged genomic sequences known as “defective viral genomes” (DVGs). Because DVGs often lack critical elements needed for replication and formation of new viral particles, virions containing DVGs can only complete a replication cycle if they co-infect a cell together with respective …
