WebSep 9, 2024 · The viral proteins considered to be the “core” RTC are the RNA-dependent RNA polymerase (RdRp; nsp12), the nsp13 helicase and processivity factors nsp7 and nsp8 (Sola et al., 2015) (Figure 3). The CoV nsp13 is a helicase that can unwind dsRNA in a 5′ to 3′ direction with the resulting single-stranded RNAs (ssRNAs) probably serving as templates … WebProofreading by DNA polymerase corrects errors during replication. Some errors are not corrected during replication, but are instead corrected after replication is completed; this type of repair is known as mismatch repair …
