Chromatin prokaryotic
WebSep 3, 2024 · Chromatin can be found in the nucleus of a eukaryotic cell or freely floating in the cytoplasm of prokaryotic cells. Upon cell division, chromatin condenses to a structure called chromosomes. WebNucleosomes are made up of eight histones, which are a group of related proteins found in eukaryotes. Nucleosomes are an important component of the chromatin (the material that chromosomes are made of). Nucleosomes help to organize, compact, and regulate the DNA. This is also discussed in this video starting around.

Chromatin is a dynamic structure capable of changing its … WebIn eukaryotes, DNA is tightly wound into a complex called chromatin. Thanks to the process of chromatin remodeling, this complex can be "opened" so that specific genes are expressed.
WebChromatin modification (or chromatin remodeling) is the first step in the regulation of eukaryotic gene expression, and it happens before transcription. Chromatin modification … WebChromatin is a genetic material or a macromolecule comprising DNA, RNA, and associated proteins, which constitute chromosomes in the nucleus of a eukaryotic cell. This chromatin is located within the cell nucleus. The main functions of this genetic material include: Preventing DNA damage. Tightly packing the DNA to fit into the cell.
