Mg2+ complexes with the single stranded DNA that is to be amplified, and becomes the substrate of DNA polymerase. In other words, it helps in the binding of primer (and the subsequent target DNA) to the template DNA. Different volume of Mg2+ exert different complex-forming capabilities, and thus affects the end product of PCR.
MgCl2 is used in PCR because it acts as a cofactor for the DNA polymerase enzyme, thereby enabling the enzyme to function optimally. The Mg2+ ions help stabilize the DNA strands and facilitate the binding of primers to the template DNA during the amplification process. The concentration of MgCl2 can affect the efficiency and specificity of the PCR reaction.
PCR is a biotechnological method to amplify your gene (DNA) of your interest. It produce millions of your DNA fragments hence used in cloning. There are variants of this method using the same thermocycling principle such as touch down PCR, gradient PCR, RFLP, multiplex PCR, Q PCR, RT PCR and so on.
PCR stands for Polymerase Chain Reaction.
yes mgcl2 is aqous solution
Mg + MgCl2
MgCl2 Mg = 24.30 2Cl = 70.906 FW = 95.21 (Remember SigFigs) 12.5g ÷ 95g of MgCl2 = 0.131 moles of MgCl2 200mL = 0.200 L 0.131 moles of MgCl2 ÷ 0.200 L = 0.656 Molar Concentration
it enhance the reaction
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.

MgCl2 is magnesium chloride.
MgCl2=95grams per mole so 105g/95g is 1.10 mols of MgCl2
MgCl2 Molarity = moles of solute/Liters of solution ( 250 ml = 0.250 L ) Get moles MgCl2 80 grams MgCl2 (1 mole MgCl2/95.21 grams) = 0.8402 moles MgCl2 Molarity = 0.8402 moles MgCl2/0.250 Liters = 3.4 M MgCl2 ----------------
The use of dNTP is PCR and multiplex PCR
PCR stands for Polymerase Chain Reaction.
The synthesis equation for MgCl2 is Mg + Cl2 -> MgCl2. The decomposition reaction is MgCl2 - heat-> Mg + Cl2.
