Chromatin is a complex of macromolecules composed of DNA, RNA, and protein, which is found inside the nucleus of eukaryotic cells. Chromatin exists in two forms: heterochromatin (condensed) and euchromatin (extended).
What two macromolecules make up chromatin?
Chromatin is the material that makes up a chromosome that consists of DNA and protein. The major proteins in chromatin are proteins called histones.
What is chromatin composed of?
Chromatin is a complex of DNA and proteins that forms chromosomes within the nucleus of eukaryotic cells. Nuclear DNA does not appear in free linear strands; it is highly condensed and wrapped around nuclear proteins in order to fit inside the nucleus.
What macromolecule that makes up the structure of chromatin and chromosomes?
Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.
What is the difference between DNA and chromatin?
The DNA is packaged by special proteins called histones to form chromatin. The chromatin further condenses to form chromosomes.
|Difference between Chromosomes and Chromatin|
|Composed of nucleosomes||They are condensed chromatin fibers|
What is chromosome structure and function?
Chromosomes, the thread-like structures are located inside the nucleus of all animal and plant cells. … Chromosomes are composed of DNA, histones, non-histone proteins, RNA and nucleic acids that help in the overall functioning of the cell for growth, reproduction and survival.
