What is the description of a chromatin fiber?
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.
Are chromosome more condense than chromatin?
Yes, you can think of chromosomes tightly wound up DNA and chromatin as unwound DNA.
How does chromatin fiber work?
Chromatin fiber is a complex of DNA and proteins, primarily histones, that packages and organizes genetic material within the nucleus of eukaryotic cells. The DNA wraps around histone proteins to form nucleosomes, which then coil and fold to create higher-order structures, resulting in the compact chromatin fiber seen during cell division. This organization facilitates efficient gene regulation, DNA replication, and repair, while also allowing access to specific genes when needed. The degree of chromatin compaction can vary, influencing gene expression and cellular functions.
How is a chromosome different from chromatin and how are they similar?
Chromosomes exist [in interphase] as de-condensed, or free, potential chromatin; while chromatin is chromosomes that are condensed [wound] around histone proteins. This condensation, or packing, of the chromosomes occurs in two stages: first the Dna strand is wound around Histone proteins that then spiral into The Ten Nanometer Fiber. This spiraled compact 10 nm fiber is then further wound up into the Thirty Nanometer Fiber, the chromatin, which is then further folded [condensed] into The Chromosomes.
What is DNA called when it shortens and thickens?
When DNA shortens and thickens, it is called chromatin. Chromatin is a complex of DNA and proteins that condenses to form chromosomes during cell division.

Loosely coiled fiber containing DNA and protein with in nucleus?
Chromatin is the loosely coiled fiber found within the nucleus of a cell, containing DNA and proteins such as histones. This structure helps package and organize the genetic material in a way that allows for efficient regulation of gene expression and replication.
State how DNA is packaged in chromatin?
From loose to tight in order of DNA, histones, nucleosomes, 30 nm fiber, looped domains (300 nm fiber), then metaphase chromosome (700 nm chromatid).
What is the relation to DNA and chromatin?
DNA makes up a chromatin.

What form is DNA during interphase?
During interphase the DNA is in loose form. It makes the chromatin inside the nucleus. The chromatin allow access to RNA and DNA polymerases that transcribe and replicate DNA.During interphase the DNA is in loose form. It makes the chromatin inside the nucleus.

Is naked DNA called chromatin?
No, naked DNA is not called chromatin. Chromatin refers to the complex of DNA and proteins that make up a chromosome. Naked DNA refers to DNA that is not associated with proteins or organized into chromatin structure.
What is the structure of chromatin, specifically referring to DNA wrapped around histone proteins?
Chromatin is a complex structure made up of DNA wrapped around histone proteins. The DNA is tightly wound around the histones, forming nucleosomes. These nucleosomes are further organized into higher order structures, ultimately creating the chromatin fiber. This structure helps to compact and regulate the expression of genes within the DNA.
What is DNA in an uncondensed form?
In its uncondensed form, DNA exists as long, coiled strands known as chromatin. Chromatin consists of DNA wrapped around histone proteins, which help regulate gene expression and DNA packaging. This structure allows the DNA to be accessible for various cellular processes such as transcription and replication.
What is filled with DNA is called chromatin?
The nucleus of the cell is filled with DNA in the form of chromatin.
