## Abstract Flow cytometry indicated that significant amounts of dsRNA were accumulated in HeLa S3 cells blocked at or near G~1~/S boundary by hydroxyurea (HU) or excess thymidine (TdR). The dsRNA/DNA ratio increased in these cells in a manner characteristic of unbalanced cell growth. In HUβtreated
## Abstract The effect of chlorambucil on the colonyβforming ability of HeLa cells following either treatment for 1 h or continuous treatment has been measured. Concentrations of chlorambucil which had only minimal effects on cell survival inhibited the rate of DNA but not RNA and protein synthesis
