What is the function of sodium citrate in DNA isolation?
Sodium ions neutralize the negative charge of the DNA backbone (phosphates) making the DNA less hydrophilic (less likely to be solubilized) in the wash solution
The function of Wash solution in plasmid DNA extraction?
Plasmid isolation has a step called washing step that carried out in the column in which the plasmid DNA are already bind. There are two wash solution, first one endo wash buffer that wash the traces of bacterial membrane remnants such as LPS. Wash buffer two has ethanol wash off any protein contaminants present on the column. These wash steps ensure the purify of isolated plasmid DNA.
Role of spooling in blood DNA isolation?
spooling of the DNA results from the addition of the ethanol which is insoluble in the solution. after we get he DNA in the form of spooling structure the solution is centrifuged. so we get the DNA.
What is the use of resuspension solution in DNA isolation?
Resuspension buffer (solution I) is used for the isolation of plasmid DNA by alkaline lysis method. Bacterial cells, obtained from the culture (liquid culture or colonies grown on agar plate), is resuspended in this buffer. The purpose of this buffer is to provide an optimal starting pH (pH 8.0) and an ideal condition for subsequent lysis.
Use of agrose in DNA isolation?
Agarose is not used in DNA isolation. Agarose is used to prepare a gel in which DNA fragments can be separated based on size

Role of CTAB in DNA isolation?
It sequester carbohydrates in the solution

What does RNase solution do in the Isolation of genomic DNA from Negative bacteria?
Digests RNA molecules
Why you use TEG Buffer in isolation of plasmid DNA?
Good morning, the TEG contains TRIS to keep pH of solution constant, EDTA to capture ions Ca2+ and Mg2+ in solution (which may interfere in the isolation of DNA) and Glicose/Dextrose (+- 50 mM) is used to increase the osmolarity of solution and lysin the cell. the cell swells to bursting and the DNA remains in solution.

What is the principle involved in the isolation procedure?
DNA isolation is a based on the principle of purification. DNA samples are isolated through the use of physical and chemical methods. Friedrich Miescher conducted the first isolation of DNA in 1869.
Role of Triton x-100 in DNA extraction?
it iS A ionic detergent disrupts bonds between lipids and fosters the isolation of DNA....
Role of sucrose in DNA isolation from human blood?
Sucrose performs the function of osmoregulation in the protocol of DNA isolation from blood
What is role of Cetyl trimethyl ammonium bromide in DNA isolation?
it act as as a cationic detergent for the isolation dna from the given sample
