WebSep 1, 2024 · Some RNA viruses (i.e., picornaviruses) use a protein to prime RNA replication. A tyrosine hydroxyl group on the primer protein (VPg) is linked to GTP to serve as the first nucleotide in the new strand. The protein interactions between VPg, RdRp, and the RNA template form a stable initiation complex (Chapter 11: Family Picornaviridae). • WebTranscription uses one of the two exposed DNA strands as a template; this strand is called the template strand.The RNA product is complementary to the template strand and is almost identical to the other DNA strand, called … WebApr 13, 2024 · Viral RNA replicates to form viral DNA with the help of the enzyme \( x \) .
