Chromatin is a complex of DNA and proteins that forms chromosomes within the nucleus of eukaryotic cells. During cell division, the structure of the chromatin and chromosomes are visible under a light microscope, and they change in shape as the DNA is duplicated and separated into two cells.

What is chromatin kid definition?
Chromatin is a way for DNA to take up less space in the nucleus of the cell. Loose DNA is called chromatin when it becomes tighter; this is done by wrapping itself around structures called histones. Histones are small molecules that look like little balls.
What is chromatin and what is its structure?
Chromatin 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.
What is chromatin function?
Chromatin is located in the nucleus of our cells. The primary function of chromatin is to compress the DNA into a compact unit that will be less voluminous and can fit within the nucleus. Chromatin consists of complexes of small proteins known as histones and DNA.
What are chromosomes and chromatin?
The main difference between chromatin and chromosome is that chromatin consists of the unravelled condensed structure of DNA for the purpose of packaging into the nucleus whereas chromosome consists of the highest condensed structure of the DNA doublehelix for the proper separation of the genetic material between
What is a chromatin quizlet?
Chromatin. An organelle which forms chromosomes during cell division. Consists of DNA, RNA, and proteins. This organelle can have different structures (e.g.an “x” or lines spinning). This organelle is only found in a eukaryote cell.
What term is also referred to as chromatin?
The DNA + histone = chromatin definition: The DNA double helix in the cell nucleus is packaged by special proteins termed histones. The formed protein/DNA complex is called chromatin. The basic structural unit of chromatin is the nucleosome.
What is the function of chromatin in animal cell?
Its functions are to package DNA into a smaller volume to fit in the cell, strengthen the DNA to allow mitosis and meiosis, and serve as a mechanism to control expression. The chromatin is found within the nucleus of eukaryotic cells and the cytoplasm of prokaryotic cells.
How do chromosomes relate to chromatin?
Explanation: Chromatin is DNA packaged by histones. When chromatin is condensed and further organized, we have chromosomes. Chromosomes are paired whereas chromatin is not.
Which of the following definitions best describes the term chromatin?
which of the following definitions best describes the term ‘chromatin? ‘ the complex of DNA and proteins that forms the eukaryotic chromosome.
What does chromatin mean in Greek?
History and Etymology for chromatin borrowed from German Chromatin “dense part of the cell nucleus that is easily stained,” from Greek chrōmat-, chrôma “color” + German -in -in entry 1.
What is chromatin class9?
Chromatin is a genetic material or a macromolecule comprising of DNA, RNA, and associated proteins, which constitute chromosomes in the nucleus of an eukaryotic cell. Support the DNA molecule to permit the process of cell cycle – meiosis and mitosis.
What is chromatin like analogy?
Analogy: Chromatin are like manuals in a factory to teach workers how to make the product. A cell membrane is a thin membrane (a double layer of lipids) enclosing the cytoplasm of a cell.
Does chromatin have RNA?
Our results indicate that purified chromatin contains significant amounts of RNA (2%–5% of total nucleic acids).
What is the main difference between chromatin and chromosome?
Chromatin is a complex formed by histones packaging the DNA double helix. Chromosomes are structures of proteins and nucleic acids found in the living cells and carry genetic material. Chromatin is composed of nucleosomes. Chromosomes are composed of condensed chromatin fibers.
