A chromosome is a package of DNA containing part or all of the genetic ... In the nuclear chromosomes of eukaryotes, the uncondensed DNA exists in a semi-ordered ...
Chromosome scaffold has important role to hold the chromatin into compact chromosome. Chromosome scaffold is made of proteins including condensin, topoisomerase IIα and kinesin family member 4 (KIF4) [7] Dinoflagellates are very divergent eukaryotes in terms of how they package their DNA. Their chromosomes are packed in a liquid-crystalline ...
Eukaryotic chromosome structure refers to the levels of packaging from raw DNA molecules to the chromosomal structures seen during metaphase in mitosis or meiosis. Chromosomes contain long strands of DNA containing genetic information.
Chromosome scaffolds play an important role to hold the chromatin into compact chromosomes. Loops of 30 nm structure further condense with scaffold, into higher order structures. [ 19 ] Chromosome scaffolds are made of proteins including condensin , type IIA topoisomerase and kinesin family member 4 (KIF4). [ 20 ]
General model for duplication of heterochromatin during cell division Microscopy of heterochromatic versus euchromatic nuclei ().. Heterochromatin has been associated with several functions, from gene regulation to the protection of chromosome integrity; [13] some of these roles can be attributed to the dense packing of DNA, which makes it less accessible to protein factors that usually bind ...
The cells of those born male contain an X chromosome and a Y chromosome that make a pair and give instructions on which genes should be expressed in the body, the researchers said.
