How to use chromatins in a sentence? Find typical usage patterns (collocations)/phrases/context for "chromatins" and check conjugation/comparative form for "chromatins". Mastering all the usages of "chromatins" from sentence examples published by news publications.
The first definition allows for "chromatins" to be defined in other domains of life like bacteria and archaea, using any DNA-binding proteins that condenses the molecule. These proteins are usually referred to nucleoid-associated proteins (NAPs); examples include AsnC/LrpC with HU. In addition, some archaea do produce nucleosomes from proteins homologous to eukaryotic histones.

Evidence for such a structure was recognised as long ago as 1948 (Zbarskii and Debov), and consequently many proteins associated with the matrix have been discovered. The presence of intra-cellular proteins is common ground, and it is agreed that proteins such as the Scaffold, or Matrix Associated Proteins (SAR or MAR) have some role in the organisation of chromatins. There is evidence that the nuclear matrix is involved in regulation of gene expression in Arabidopsis thaliana.

Kostoff predicted that the discs (bands) which he observed were "the actual packets in which inherited characters are passed from generation to generation." The hereditary nature of these structures was not confirmed until they were studied in Drosophila melanogaster in the early 1930s by German biologists Emil Heitz and Hans Bauer. In 1930, Heitz studied different species of Drosophila (D. melanogaster, D. simulans, D. hydei, and D. virilis) and found that all their interphase chromatins in certain cells were swollen and messy.

That neocentromeres and conventional centromeres do not share consistent chromatin environment should also be taken into account in questioning the epigenetic regulation of centromere formation. The N-terminal tails of histones can be modified in several ways, including phosphorylation, acetylation, methylation and ubiquitination. Although certain histone modifications at centromeres seem to serve a purpose—for example, contributing to a higher order organization of chromatins in mouse centromeres—conventional and neocentromeres share very few modifications but arguably still maintain the same function of a centromere.

To demonstrate cell death in some cases a vital dye is used to detect when cellular function is disrupted. This procedure uses living tissue that is immersed in diluted 1:0000 solution of Nile Blue Sulphate in Saline. The measurement of cell death by using this dye is observing a change of color or the formation of fluorescence. When the cell died the nucleus went through destruction stages, one of them pyknosis which lead to the release of a basic histone group and this happened when the irreversible condensation of chromatins occurred.
