Fig. 1From: Indels in SARS-CoV-2 occur at template-switching hotspotsCopy-choice recombination is the presumed primary recombination mechanism for RNA viruses. During negative strand synthesis, the replication complex and the nascent strand disassociate from the template strand. From there, the replication complex can template-switch, or reassociate with a homologous or replicate template strandBack to article page
