Active gene sequences are present in the nucleosomal fraction of chromatin. Histones are attached to the DNA of transcribing non-ribosomal genes, and EM images suggest that their conformation is related to that of nucleosomes, or is readily converted to that structure on preparation for microscopy.

Structure of Chromatin in Spermatozoa
2013The specialized structure of the sperm chromatin has a dual function - first to protect the DNA from damage during storage and transport to the oocyte, and then to enable a rapid and complete unpacking of the undamaged paternal genome in the ooplasm. It is evident that zinc has a pivotal role in maintaining the structural stability and in enabling a ...

Chromatin is the physical representative of the epigenome. Histones are the main protein component of chromatin and form octamer cores, around which genomic DNA is wrapped. These nucleosomes are the regularly repeating units of chromatin, but they can vary from one genomic region to the other by (i) different post-translational modifications of amino ...

Chromatin from calf thymus has been reinvestigated.If the extraction procedure of Zubay and Doty is altered through the omission of EDTA and the resulting fibrils are picked up on grids by the method of Koller et al from a solution containing no added salt, one observes fibrils of diameter about 230 Å. (Figure A). This is the same diameter as was found

The Structure and Function of Chromatin
1972Biochemical and genetic studies have produced a vast fund of knowledge concerning gene action and regulation in prokaryotes. In these organisms the DNA is exposed rather nakedly to the world, protected primarily by the cell membrane. In eukaryotes the DNA seems far better shielded, being enmeshed in histone and nonhistone proteins and sequestered ...
