What is the function of sodium citrate in DNA isolation?
Sodium citrate is used in DNA isolation to prevent DNA degradation by chelating divalent cations such as magnesium and calcium, which can act as cofactors for DNases. By binding these ions, sodium citrate helps to stabilize the DNA and protect it from enzymatic degradation during the isolation process.
Role of EDTA in DNA isolation?
it is chealeting agent and has great affinity with metal ions and mg- ions present in dnase as a cofactor and responsible for dnase action that degreded DNA hear edta bide with mg- ions and stop the action of dnase.
What do magnesium ions do?
Magnesium ions are essential for various biological processes in the body, including muscle and nerve function, blood sugar regulation, and bone health. They also play a role in energy production and DNA synthesis. Additionally, magnesium helps to maintain normal heart rhythm and supports the immune system.
Role of peg in plasmid DNA isolation?
PEG (polyethylene glycol) is commonly used in plasmid DNA isolation to precipitate the DNA. When mixed with DNA in a high-salt buffer, PEG causes the DNA to aggregate and precipitate out of solution. This allows for separation of the plasmid DNA from other cellular components, making it easier to purify the DNA.
Role of sucrose in DNA isolation from human blood?
Sucrose is used in DNA isolation from human blood as a protective agent to help maintain the integrity of the DNA during the isolation process. It helps to stabilize the DNA by providing a protective barrier against enzymes and other degradation factors present in the blood sample. Additionally, sucrose can aid in the separation of DNA from other cellular components during the isolation procedure.

What is the role of NaCl and edta in DNA isolation?
NaCl provides Na+ ions that will block negative charge from phosphates on DNA. Negatively charged phosphates on DNA cause molecules to repel each other. The Na+ ions will form an ionic bond with the negatively charged phosphates on the DNA, neutralizing the negative charges and allowing the DNA molecules to come together
Role of CTAB in DNA isolation?
It sequester carbohydrates in the solution
What is the role of SE-VEG in DNA isolation?
the role seveg in plant DNA extractions is to remove chlorophyll and similar pigments
What is the role of Mg ion in activation of restriction enzyme?
most restriction enzymes require magnesium ions for their activation, local restriction enzyme activity can be controlled by the local concentration of magnesium ions. Applying a direct current (dc) voltage to a needle electrode of metallic magnesium made it possible to control the local magnesium ion concentration at the tip of the needle. The restriction enzyme was activated only when magnesium ions were electrochemically supplied.
Role of magnesium chloride in PCR?
Magnesium chloride is a crucial component in the polymerase chain reaction (PCR) as it is required for the activity of the DNA polymerase enzyme. Magnesium ions help stabilize the DNA template-primer complex and are essential for the enzymatic activity of the DNA polymerase, allowing for successful DNA amplification during PCR. The optimal concentration of magnesium chloride can vary depending on the specific DNA polymerase being used and the PCR conditions.
What is the Role of NaCl in DNA isolation?
NaCl provides Na+ions which form ionic bond with the negatively charged phosphate of DNA,thus neutralizing the effect of negative ,negative repulsion of DNA and helps the DNA molecules to come closer and compact to simplify our process of DNA isolation...

What is the function of ethylene diamine tetraacetic acid in DNA isolation?
Ethylene diamine tetraacetic acid (EDTA) is a chelating agent commonly used in DNA isolation to sequester divalent metal ions, such as Mg2+, that are required by nucleases to degrade DNA. By removing these metal ions, EDTA helps to inhibit the activity of nucleases and stabilize the DNA during the isolation process.
What is the role of 2-mercaptoethanol in the isolation of genomic DNA from a plant source?
It is an antioxidant.
