Pirates were the kings of the seas in the 17th and 18th centuries, apart from Mary Read and Anne Bonny who were the Queens of the ocean! See how much you know about one of the most well known pirates - Blackbeard.
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.
Linker histones such as H1 and its isoforms are involved in chromatin compaction and sit at the base of the nucleosome near the DNA entry and exit binding to the linker region of the DNA. Non-condensed nucleosomes without the linker histone resemble beads on a string of DNA under an electron microscope.he string is the DNA, while each bead in the nucleosome is a core particle. The nucleosome core particle is composed of DNA and histone proteins. Partial DNAse digestion of chromatin reveals its nucleosome structure.
