although the cloned poly ( c ) tracts were considerably shorter than those found in viral rna from mengovirus ( c50uc10 ) or emc virus ( c115ucuc3uc10 ) , the growth characteristics of the progeny viruses in hela cells were indistinguishable from those of the parental viruses , indicating the length of this tract does not play a significant restrictive role for cardiovirus infectivity in tissue culture .
