RESUMO
A functional gene A product of phi X174 was found to be required at the stage of single-stranded DNA synthesis. A precursor complex that synthesizes single-stranded DNA (50S complex [Fujisawa and Hayashi, 1976]) was isolated from cells infected with wild-type or with temperature-sensitive gene A mutant phage. Proper cleavage of the single-stranded viral DNA did not occur in cells infected with the temperature-sensitive gene A mutant under restrictive conditions. This resulted in (i) accumulation of linear viral DNA molecules of 2 units in length in the 50S complex and (ii) cessation of elongation of viral-strand DNA after one complete cycle of single-stranded DNA synthesis.
