Did you know?
WebIn eukaryotic cells, the first stage of gene expression control occurs at the epigenetic level. Epigenetic mechanisms control access to the chromosomal region to allow genes to be turned on or off. These mechanisms control how DNA is packed into the nucleus by regulating how tightly the DNA is wound around histone proteins. WebConsider these fundamental facts about the eukaryotic nuclear genome. It is linear, as opposed to the typically circular DNA of bacterial cells. It conforms to the Watson-Crick double-helix...
