Abstract:
:The RNAs of replication-defective murine and primate type C transforming viruses were analyzed for the presence of nucleotide sequences homologous to the genomes of their respective helper type C viruses by using DNAs complementary (cDNA) to either the 5'-terminal (cDNA5') or total (cDNAtotal) nucleotide sequences of the helper virus RNA. The defective viruses examined have previously been shown to vary in their ability to express helper viral gag gene proteins. With cDNAtotal as a probe, these transforming viruses were shown to vary in their representation of helper sequences (15 to 60% hybridization of cDNAtotal). In striking contrast, 5'-terminal-specific sequences of the helper virus were conserved in the RNAs of every transforming virus tested (is greater than 80% hybridization of cDNA5'). These findings suggest a critical role for these sequences in the life cycle of the defective transforming virus.
