WebMay 1, 2024 · It is a complex process involving the action of several viral and host proteins in order to perform RNA polymerization, proofreading and final capping. This review provides an update of the structural and functional data on the key actors of the replicatory machinery of SARS-CoV-2, to fill the gaps in the currently available structural data, which … WebRNA polymerase has higher levels of errors in transcription compared with DNA replication. Generally, proofreading prevents or corrects errors in DNA replication, so the absence of proofreading in transcription will lead to more errors that go uncorrected.
