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.
A nucleosome is a protein complex with DNA wrapped around it. This protein complex found in the nucleosome is known as a histone. A histone is a positively charged protein. A nucleosome that is further compacted is known as chromatin. Chromatin is found in the nucleus of a cell. A chromosome is a long sequence of DNA carrying genes containing chromatin.
