Since picornaviruses spend all of their time in the cytoplasm, they must encode a polymerase (replicase) that is made from the sense strand of the infecting virus. The polymerase copies the sense strand to anti-sense which is then copied back to the sense strand that is packaged into the virus (figure 27).
