Question

What is a chromatin network?

Answer 1

Hint: The nucleus is a membrane-bound organelle that houses eukaryotic organisms' genetic material (DNA). As a result, it helps the cell preserve its integrity by promoting transcription and replication.

Complete answer:
Chromosomes are made up of a complex mixture of DNA and proteins called chromatin.
Chromatin is a DNA and protein complex that shapes chromosomes in eukaryotic cells’ nuclei. Chromatin appears as beads on a string under the microscope in its expanded form. Nucleosomes are the name for the beads.
DNA is wrapped around eight proteins called histones in each nucleosome. It’s located within eukaryotic cells’ nuclei. Heterochromatin (condensed) and euchromatin (extended) are two types of chromatin.
Heterochromatin is a form of DNA that is tightly packed or condensed and comes in a variety of shapes and sizes. Between the two extremes of constitutive heterochromatin and facultative heterochromatin, both varieties exist on a spectrum. Gene expression is influenced by both of these factors.
Euchromatin is a form of chromatin that is densely packed with genes and frequently under active transcription. Within the cell nucleus, euchromatin is the most active component of the genome. The human genome is euchromatic in $92\%$ of cases.
Within cells, chromatin folds into distinct structures known as chromosomes. During interphase, chromatin is at its least concentrated and tends to be strewn around the nucleus. During prophase, chromatin condensation starts, and chromosomes become noticeable.
The nucleus houses the cell's DNA and controls ribosome and protein synthesis. The nucleolus is a condensed region of chromatin found within the nucleoplasm where ribosome synthesis takes place. The nucleoplasm stores chromatin, which is made up of DNA wrapped around histone proteins.

Note:
1) When DNA binds with histone proteins the structure is called chromatin.
2) The chromatin is of two types.
3) Out of the two types of chromatin, one is functional and the other is not.
