Nucleosomes: Structure and Function. Abstract. The structure of the nucleosome core particle, the basic repeating unit in eukaryotic chromatin, allows us to view the role of histones in regulating transcription, and in assembling specialized chromatin domains in a structural context.
Structure & Function. The nucleolus is a very dense structure inside the nucleolus. Depending on what the cell is or how big it is, the cell may have more than one nucleolus because of how many ribosomes it needs.It doesn't have a membrane so DNA inside the nucleus can easily be transferred to the nucleolus to transcript it to rRNA.epending on what the cell is or how big it is, the cell may have more than one nucleolus because of how many ribosomes it needs.
