WebJul 30, 2024 · Unlike prokaryotic cells, eukaryotic cells can regulate gene expression at many different levels. Eukaryotic gene expression begins with control of access to the DNA. This form of regulation, called epigenetic regulation, occurs even before transcription is initiated. Learning Objectives.

WebIn nearly all species, the bulk of MCMs are constitutively located in the nucleus throughout the entire cell cycle, with their chromatin association, rather than nuclear localization, subject to cell cycle regulation (see, e.g., references 86, 121, 153, 159, 199, 240, 247, 278, 300, and 318). However, there is still a role for the nuclear ...
WebAug 2, 2024 · Chromatin is a combination of DNA and histone proteins that form the chromosomes in eukaryotic cells.
