Summary
Nucleolar fusion and nucleolus formation occurred simultaneously, immediately after mitosis, in cultured human lymphocytes. Evidence is presented that in late telophase and post-telophase, the individual nucleolar organising site includes two components, represented in post-telophase by the nucleolus and its attached process; that fusion can be either directly between the nucleoli or via the processes; and that the latter type of fusion persists into metaphase as acrocentric associations, whilst the former is lost.
