Any process that modulates the frequency, rate or extent of cellular DNA-templated transcription.

The progressive compaction of dispersed interphase chromatin into threadlike chromosomes prior to mitotic or meiotic nuclear division, or during apoptosis, in eukaryotic cells.

Any process that stops, prevents, or reduces the frequency, rate or extent of chromatin silencing.

Any process that stops, prevents, or reduces the frequency, rate or extent of DNA recombination.

A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.

The ordered and organized complex of DNA, protein, and sometimes RNA, that forms the chromosome.

A complex comprised of DNA wound around a multisubunit core and associated proteins, which forms the primary packing unit of DNA in the nucleus into higher order structures.

The ordered and organized complex of DNA, protein, and sometimes RNA, that forms the chromosome in the nucleus.

A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.

A macromolecular complex containing both protein and DNA molecules.

A highly compacted molecule of DNA and associated proteins resulting in a cytologically distinct nuclear chromosome.
