WebEukaryotic chromosomes consist of DNA tightly wound around clusters of histone proteins. Chromatin consists of all the DNA in the nucleus, as well as its associated proteins. There are three basic layers of chromatin … WebIn eukaryotes, these proteins include the histones, a group of basic (positively charged) proteins that form “bobbins” around which negatively charged DNA can wrap. In addition to organizing DNA and making it more compact, histones play an important role in determining which genes are active.
WebThe nucleus stores chromatin (DNA plus proteins) in a gel-like substance called the nucleoplasm. The nucleolus is a condensed region of chromatin where ribosome synthesis occurs. ... In eukaryotes, chromosomes are …
Chromatin consists of complexes of small proteins known as histones and DNA. Histones help organize DNA into structures called nucleosomes by providing a base on which the DNA can be wrapped around. A nucleosome consists of a DNA sequence of about 150 base pairs that is wrapped around a set of … See more Chromatin within a cell may be compacted to varying degrees depending on a cell's stage in the cell cycle.
