RESUMO
For the first time, we present evidence with restriction enzymes HpaII and MspI which indicates that the proviral DNA sequence of avian sarcoma virus is modified by methylation in a nonpermissive rat cell line but not in permissive chicken cells. Some of the endogenous viral sequences in the permissive cells were also methylated. No 5-methylcytosine could be detected in the unintegrated viral DNA.
