<div>New research by German scientists has uncovered another form of coronavirus polymerase. The current polymerase thought to be used for the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a viral RNA-dependent RNA polymerase (RdRp) for replication and transcription. It contains a monomeric enzyme with the catalytic subunit nsp12, two copies of subunit nsp8, and one copy of subunit nsp7.</div>
