dc.description.abstract | Invisible compartments, identified rather by their activities than by their morphology, seem to operate in the nucleus. These compartments interrelate somehow, including mediation by the nuclear matrix. As our knowledge about the nucleus increases, more paradoxes become evident. We here consider some of them: 1) the well-known C-paradox of Cavalier-Smith, conceming the disproportionate amount of nuclear DNA content in comparison with the amount of DNA potentially able to transcribe; 2) the DNA folding in the chromatin fibre and its superorganization within the nucleus, which seems to be in opposition with the transcribing and self-replicating activities; 3) the elusive role of the DNA sequences with different degrees of repetitivity; and 4) the compartmentalization in the nucleus and how it relates to transcription, processing and transport of transcripts, and to DNA reduplication. We conclude by introducing the concept of species specific, minimal, but essential genome components, ¡.e. the elusive few thousand DNA bases that, in our hypothesis, act as a functional bridge between the nuclear matrix and chromatin. | es |
