Molecular Reorganization During Nuclear Differentiation in Ciliates

  • Chapter
Germ Line — Soma Differentiation

Part of the book series: Results and Problems in Cell Differentiation ((RESULTS,volume 13))

Abstract

Differentiation denotes the process by which cells of multicellular organisms become different from one another. The closely related process by which nuclei become functionally and/or structurally different from one another can be called nuclear differentiation. Nuclear differentiation is a well-known, but often poorly understood phenomenon. For instance, large differences exist between gamete nuclei, e.g., sperm nuclei and somatic nuclei of the same organism, with regards to nuclear size, chromatin condensation, transcriptional activity, structure of the nuclear lamina, and many other characteristics. But differences in nuclear structure and in the organization of the genetic material also occur between different somatic nuclei. Differing amounts of eu-and heterochromatin, DNA rearrangements during cellular development, or amplification of certain genes may give rise to the existence of nuclei which differ from one another despite their common origin from one zygote nucleus.
