Histones bind to DNA at specific sites and make DNA coil around them to form nucleosomes. It results in the formation of 10 nm fibre which further coils to form a a solenoid of 30 nm thickness. This coiling is prolonged during mitosis and fiber gets thickened and shortened to form chromosomes.

What are Eukaryotic cell organelles that synthesize proteins and process proteins called?
The organelles in eukaryotic cells that synthesize and process proteins are called ribosomes and the endoplasmic reticulum, respectively. Ribosomes are responsible for protein synthesis, while the endoplasmic reticulum aids in protein folding, modification, and transport.
What is the autogenic hypothesis of the origin of the eukaryotic cell?
Autogenic means produced from within, or self-generating. Therefore the 'autogenic hypothesis' is most likely to be that the organelles and structures of a Eukaryotic cell were self-generated by a Prokaryotic cell - and this is how Eukaryotic cells were created. The theory of Endosymbiosis is much more widely accepted.
Why do molecular biologists use yeast as opposed to bacteria for expressing genes of interest?
molecular biologists can avoid eukaryotic-prokaryotic incompatibility by using eukaryotic cells such as yeasts, rather than bacteria, as hosts for cloning and/or expressing eukaryotic genes of interest. source: Campbell Biology 7th edition
What is the definition of rough endoplasmic reticulum?
Rough endoplasmic reticulum, (RER),an organelle composed of an interconnected network of internal membranes within eukaryotic cells; rough ER is associated with ribosomes, whereas smooth ER lacks ribosomes.
Is protein folding a spontaneous process?
Yes, protein folding is a spontaneous process that occurs naturally within cells.
Explain the role of chaperone proteins in protein folding?
I don't have a clue, what do you think?
How do you make the twin towers on the 20 dollar bill?
by folding it in various places I cant explain
What is the role of molecular chaperones in the normal eukaryotic cell?
They prevent inappropriate association or aggregation of exposed hydrophobic surfaces and direct their substrates into productive folding, transport or degradation pathways.

Describe what occurs at a destructive boundary. Explain what folding is and give an example of a mountain region formed by folding.?
At a destructive boundary, two tectonic plates move towards each other, causing one to be forced beneath the other in a process known as subduction. This can result in the formation of mountain ranges through folding, which is the bending and deformation of rock layers due to compression forces. The Himalayas in Asia are an example of a mountain region formed by folding at a destructive boundary between the Indian Plate and the Eurasian Plate.
What is the word for folding arms?
folding you arms!
Is folding paper origami?
sometimes origami is folding paper or folding coloured card but sometimes it isn't
What are the advantages of a folding machine?
advantaags of folding machines
Why endopladmic reticulum is present in all eukaryotic cells but not in prokaryotic cells?
The endoplasmic reticulum (ER) is present in all eukaryotic cells because it plays a crucial role in the synthesis, folding, and transport of proteins and lipids, which are essential for complex cellular functions. Eukaryotic cells have compartmentalized structures, allowing for specialized functions in different organelles, such as the ER. Prokaryotic cells, on the other hand, lack membrane-bound organelles and have a simpler structure, relying on different mechanisms for protein synthesis and cellular processes, making the ER unnecessary.
Who created iris folding?
Iris folding started in Holland.
What does 'folding green' mean?
