For DNA to precipitate down when ethanol added it needs a higher salt concentration which will allow it to precipitate more accurately, hence this salt is given in form of Na acetate which is the best salt for the purpose or else NaCl

What is the role of sodium acetate buffer in casein estimation from milk?
pH of sodium acetate buffer is 4.6 and most of the proteins have 4.8 isoelectric pH (pI), so buffer maintains the pI of casein in the casein estimation from milk
Role of sodium acetate in DNA isolation?
potassium acetate (KAc) is added, which does three things: a. Circular DNA is allowed to renature. Sheared cellular DNA remains denatured as single stranded DNA (ssDNA). b. The ssDNA is precipitated, since large ssDNA molecules are insoluble in high salt. c. Adding sodium acetate to the SDS forms KDS, which is insoluble. This will allow for the easy removal of the SDS from your plasmid DNA.
What food contains acetate?
You can find acetate in many foods since it plays more than one role such as cheese and vinegars.
What is the role of calcium chloride in transformation?
addition of calcium chloride to a cell suspension promotes the binding of plasmid DNA to the cell surface ,which can then pass into the cell.
What happens when you open the sodium channels in the membrane of a neuron?
When this occurs, the membranes potenial drops, as potassium and sodium diffuse with their gradient.
What is the role of sodium acetate in DNA extraction?
sodiom acetat reaction with membrane protein and cause that persipitate and help to dna isolation
Role of Glacial acetic acid in plasmid isolation?
to neutralise the alkaline conditions.
What is the Role of RNAase in plasmid preparation?
In plasmid isolation RNA behaves as an unwanted material so to separate it out RNAase is required which breaks down the RNA. This is done to get pure quality of the product.
What is the role of NaCl in RNA isolation?
The role of NaCl or sodium chloride in RNA isolation is part of the denaturing process. It is often called the wash step.
What is the role of tris-hcl sodium bisulfite and sodium bicarbonate in genomic DNA isolation?
than podo
Role of NaOH in plasmid DNA isolation?
Plasmid isolation involves growing the plasmid under conditions that are suitable for genes to come into play. For example the gene for ampicillin resistance; the bacteria with plasmids are placed with ampicillin so their genes can be seen for those who survived. Sodium hydroxide acts a detergent in the extraction process. A detergent's main role is to break down cell walls and cell membranes. How so? They act as poking holes into membranes. However, for the isolation of plasmid, the NaOH acts
What is the role of sodium acetate buffer in casein estimation from milk?
pH of sodium acetate buffer is 4.6 and most of the proteins have 4.8 isoelectric pH (pI), so buffer maintains the pI of casein in the casein estimation from milk
Role of peg in plasmid DNA isolation?
it reduces the availability of solvents. that is dissociation of H+ ond OH- ions takes place. which makes the macromoleules to condence or crowd. and let to precipitate

Why do you use Tris Hcl in plasmid isolation?
The role that tris-HCI plays in plasmid isolation is to maintain the pH of the solution. This prevents degradation of the plasmids. Tris stands for the organic compound, tris(hydroxymethyl)aminomethane, which is a common pH buffer. HCl is a salt acid called hydrochloride. This is added as a buffer as well to add stabilization.
What is the role of ECORI?
It splices the genome or plasmid in a specific location (EcoRI).
Role of phenol chloroform isoamyl alcohol in plasmid DNA extraction?
The actual role of phenol chloroform isoamyl alcohol in a plasmid DNA extraction is to purify the DNA. The alcohol will act in part as a detergent.
