Native DNA precipitates as fibers when alcohol is added to a solution containing DNA. The DNA fibers can then be spooled onto a glass rod.

Will calcium chloride and potassium phosphate precipitate?
yes it will precipitate DNA if your lysing nuclei; add benzamidine hydrochloride though as a protease inhibitor.
What is the purpose to add ethanol in DNA solution?
To precipitate the DNA out of solution. It is usually done in the presence of salt, such as sodium chloride or potassium sulfate. This process is called "salting out", meaning becoming out of solution (water), which also can be done with other electrically charged molecules (ionized), including proteins.
Why do forensics wear a plastic white suit?
To avoid contaminating the evidence with their own DNA, clothing fibers, etc.
What does water droplets precipitate as?
it precipitate as rain
A solid substance that is formed in a solution is called a?
if the solution has undergone a chemical reaction and a solid forms, that solid is called a precipitate.
Why chilled ethanol is added for DNA isolation?
to precipitate extracted DNA
Why unable to precipitate DNA?
Ethanol
Why is isopropanol used to precipitate DNA and what does it do to DNA to make it precipitate?
As DNA is completely soluble in water, but not in alcohol, like isopropanol, when isoprop is added, its engaged more and more water molecule to interact, as a result, less water molecules are available to dissolve DNA, and DNA statrs ppt out.
Why does DNA uncoil and precipitate in ethanol but not in water?
BECAuse it does...
Why do you use NaCl in DNA extractions?
Sodium chloride help to precipitate and separate DNA.
Will calcium chloride and potassium phosphate precipitate?
yes it will precipitate DNA if your lysing nuclei; add benzamidine hydrochloride though as a protease inhibitor.
What is the function in the following reagents used in the extraction and precipitation of DNA?
to extract the DNA from the solution, isopropyl alcohol is mixed with the DNA solution to precipitate the same.
What qualities make evidence useful?
Dna fibers
What type of molecule has to be stripped from DNA before it will precipitate out solution?
water, H2O
What causes the DNA to precipitate and spool on the rod?
The alcohol used causes the precipitate to form due to a reaction allowing the hydrogen bonds between the nucleotides to form, which causes the DNA to become efficient packed and twisted together.
What is the function of the alcohol in DNA extraction?
DNA is not soluble in isopropyl alcohol. It will precipitate out when you add this solvent. Once out of solution you can centrifuge it down and collect the pellet of DNA.
What are long fibers of DNA and protein called?
It is called chromatin.
