Chromatin eukaryotic or prokaryotic
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. Aa Aa Aa...

Chromatin eukaryotic or prokaryotic
Did you know?
WebNucleosomes are the basic, repeating units of eukaryotic chromatin. They consist of chromosomal DNA wrapped around special DNA-binding proteins called histones. There are many examples of non-chromosomal DNA, such as plasmids, but they do not contain nucleosomes. Nuclear import is controlled by importin proteins.

Chromatin • Chemical composition of chromatin Chromatin consists of DNA, RNA and protein. • The protein of chromatin could be of two types: 1.histones and 2.non histones DNA DNA is the most important chemical component of chromatin, since it plays central role of controlling heredity and is most ...
WebTherefore, in prokaryotic cells, the control of gene expression is mostly at the transcriptional level. Eukaryotic cells, in contrast, have intracellular organelles that add to their complexity. In eukaryotic cells, the DNA is … WebThe major structures in DNA compaction: DNA, the nucleosome, the 10 nm beads on a string chromatin fibre and the metaphase chromosome. Chromatin is a complex of DNA and protein found in eukaryotic cells. [1] The primary function is to package long DNA molecules into more compact, denser structures.
WebMost of an organism’s DNA is organized into one or more chromosomes, each of which is a very long string or loop of DNA. A single chromosome can carry many different genes. In prokaryotes, DNA is typically … WebChromatin is a complex of macromolecules composed of DNA, RNA, and protein, which is found inside the nucleus of eukaryotic cells. …. The primary protein components of chromatin are histones that help to organize DNA into “bead-like” structures called nucleosomes by providing a base on which the DNA can be wrapped around.
