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.
Moreover, the presence of mRNAs and small-regulatory RNAs in the plant nucleolus and nucleolar-associated bodies is intriguing in terms of potentially novel functions in plants, broadening the roles of the nucleolus still further.ver the last 10 to 15 years, it has become clear that the nucleolus is involved in numerous other functions than ribosome biogenesis (Pederson, 1998; Rubbi and Milner, 2003; Olson, 2004; Raska et al., 2006a; Boisvert et al., 2007).
