WebMar 30, 2024 · Using extracts of synchronized proliferating HeLa cells, we show that TFIIIB activity remains low during the early part of G 1 phase and increases only gradually as cells approach S phase. As a result, the transcription of all class III genes tested is significantly less active in early G 1 than it is in S or G 2 phase, both in vitro and in vivo.
