Chromatin is a complex of DNA and protein found in eukaryotic cells. During mitosis and meiosis, chromatin facilitates proper segregation of the chromosomes in anaphase; The characteristic shapes of chromosomes visible during this stage are the result of DNA being coiled into highly condensed chromatin.
What is chromatin in nucleus?
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. Chromatin exists in two forms.
What is chromatin reticulum?
Chromatin is a complex of DNA, RNA, and protein found in eukaryotic cells. … DNA wraps around histone proteins, forming nucleosomes and the so-called “beads on a string” structure (euchromatin). punineep and 27 more users found this answer helpful. Thanks 16.
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|
Does chromatin have RNA?
Whether RNA itself plays a direct structural role in chromatin is, however, not known. Here, we report results indicating that RNA plays a general structural role in eukaryotic chromatin. Our results indicate that purified chromatin contains significant amounts of RNA (2%–5% of total nucleic acids).
Where is chromatin located in nucleus?
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 is the best definition of chromatin?
: a complex chiefly of DNA and histone in eukaryotic cells that is usually dispersed in the interphase nucleus and condensed into chromosomes in mitosis and meiosis and in which the nucleosome makes up its repeating subunits In eukaryotes, the DNA interacts with the histone proteins to form a tightly packed …
