Single molecules of DNA are long and stringy. Each cell of your body contains six feet of DNA, but it's only one-millionth of an inch wide. To fit all of this DNA into your cells, it needs to be packed efficiently. To solve this problem, DNA twists tightly and clumps together inside cells. Even when you extract DNA from cells, it still clumps together, though not as much as it would inside the cell.

What does sodium citrate do in DNA extraction?
how to make sodium citrate in 10% ethanol for DNA extraction
What is DNA extraction?
There are three basic steps in a DNA extraction, the details of which may vary depending on the type of sample and any substances that may interfere with the extraction and subsequent analysis. * Chelate divalent cations such as Mg2+ and Ca2+ to stop dnase enzymes functioning and degrading the DNA * Break open cells by grinding or sonication, and remove membrane lipids by adding a detergent. * Precipitate DNA in cold ethanol or isopropanal, DNA is insoluble in alcohol and clings together; this step also removes salt.
What does salt do in DNA extraction?
The salt neutralizes the DNA's negative charge with its positive charge while the DNA precipitates.
What is the function of ascorbic acid in DNA extraction?
removal of polyphenols
Extraction of DNA using a blender?
No-DNA exists in a microscopic level, you can't obtain it using a blender.
what causes DNA to clump together?
alcohol of any sort
What does sodium citrate do in DNA extraction?
how to make sodium citrate in 10% ethanol for DNA extraction
DNA extraction from bacteria?
DNA extraction from bacteria can be achieved in various ways. Yeast is the best resource to extract the DNA bacteria from using extreme rapid extraction method.
What is the function of CL buffer in DNA extraction?
In a DNA extraction, the purpose of a buffer is to solubilize DNA as well as RNA. Because of this, it prevents the DNA for degrading.
What is the purpose of Trichloroacetic acid in DNA extraction?
Trichloroacetic acid is used for precipitation of the DNA during its extraction.
Why grind the liver in a DNA extraction lab?
the purpose of grinding any substance during dna extraction is cell loosening.
Why extraction buffer is added for isolation of DNA?
Extraction Buffer is used to maintain pH of the solution.which prevents denaturation of DNA.
Why we can not extract DNA from RBCs?
We can not extract DNA from RBCs as they are without nucleus. only the source of DNA extraction is Leukocytes, RBCs are not good source of extraction but we can extract DNA from immature RBCs.
What is the function of 2-propanol in DNA extraction?
To achieve precipitation DNA.
What is the purpose of alcohol when extracting DNA?
According to me, we use alcohol because DNA is insoluble in alcohol, it aggregates together, giving a pellet in centrifugal and we can see a precipitated DNA with naked eyes (that we suppose to see in experiment i.e DNA extraction)....

What mesh particle size for chelex 100 is best for DNA extraction?
The 200-400 mesh size is best for DNA extraction. The smaller sizes are usually used for metal ion extraction.
