How does a eukaryotic cell compatible with its own complete DNA in the nucleus?
A. DNA is wrapped in protein, and then coils forming a more compact fiber. B. It eliminates the cell's DNA is not necessary. C. It synthesizes a second core when the first fills up. D. DNA is established in flat layers that are placed on itself, becoming similar to corrugated cardboard. E. Not sure.
Option A is the most tyical of what happens. First, is wrapped around small proteins called histones to form nucleosomes, and then help other proteins to nucleosomes stack. then the cells are super-folded proteins that make up what is just called chromatin. During mitosis, chromosomes must be especially compact (or condensed) in order to move the chromosomes in the nuclei of the daughter cells formed. These chromosomes are visible, especially with staining in a high power microscope (400-1000 X). The chromosomes of the nuclei are less compacted and is not visible unless you use any special contrast dye and an electron microscope for perhaps 10,000 or more power.

Carbon Fiber Tank, 4500 psi, 88 cu ft $839.99 DOT-approved Carbon fiber filament wound over aluminum bladder 88 cu ft 4500 psi max pressure 11.3 lbs dry weight Includes: Hose with 1/8" BSPP threads on both ends Seal washer Hose has an inline gauge (eliminates use of a yoke) Air Venturi female quick-disconnect adapter with 1/8" BSPP male threads on one end This is not a scuba tank. It’s a carbon fiber tank, which is also called an scba tank, and has a high-pressure scba valve…like the one firefighters use on their scba tanks. Many dive shops do not have the ability to fill these tanks. In some towns, the fire department has a compressor that can fill a high-pressure carbon fiber tank, as firefighters use smaller scba tanks for breathing equipment during rescues. You might want to approach your local fire department and ask if they would be willing to fill your high-pressure carbon fiber/scba tank from their compressor. Another alternative is to contact a local paintball store, as paintballers use carbon fiber tanks to fill their markers. If the only alternative you have is to fill your high-pressure carbon fiber scba tank at a dive shop, a 1/8" BSPP male to DIN female adapter (our part # AA-Z2128-300) can temporarily replace the hose on the valve adapter so the dive shop can fill your tank. |
