In linear eukaryotic chromatin, the DNA is wound around histone proteins to form nucleosomes, which then further fold into higher-order structures. These structures create loops of DNA that are organized into domains by a scaffolding of proteins such as condensins and cohesins. This looping and organization is essential for regulating gene expression and ensuring proper chromosome segregation during cell division.
A chromatin fiber is the point at which DNA in chromatin is higher then the nucleosome. Chromatin fibers occur when the linear array of the nucleosome fold into a tighter fiber.
The chromatin constitutes genes
Yes they are same.
chromatin Answer is cytosol not chromatin
Chromatin loops and nucleosomes are useful structures within a chromosome as they help to store genetic information. This allows for complex codes to be contained within chromosomes.
Yes, they do have chromatin.
Chromatin folding is primarily determined by a combination of DNA sequence elements, histone modifications, and the binding of various proteins such as transcription factors and structural proteins. These factors contribute to the formation of higher-order structures, including loops and domains, which are essential for regulating gene expression and maintaining genome integrity. Additionally, the spatial organization within the nucleus and interactions with the nuclear scaffold also play crucial roles in chromatin folding. Overall, chromatin architecture is a dynamic process influenced by both intrinsic and extrinsic factors.

I'm not a chromatin, but chromatin is the long strands of genetic material floating in the nucleus
Scaffold-associated regions (SARs) are DNA sequences that help anchor chromatin loops to the nuclear matrix, providing structural support for the overall organization of chromosomes. SARs play a role in regulating gene expression by modulating the interactions between DNA and the nuclear matrix. They are involved in maintaining the higher-order chromatin structure within the nucleus.
Chromatin are in eukariyotes.They are not in prokariyotes.

Chromatin is a mass of DNA located in the nucleus.
DNA makes up a chromatin.
The chromatin constitutes genes
When the DNA in a cell is uncoiled and spread throughout the nucleus, it is called chromatin. Chromatin consists of DNA and associated proteins that help organize and regulate gene expression within the cell.
