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 Volume of 5M HCl to make tris buffer at pH 7.5?
The formula weight is 121.5 --> this is equivalent to 1M with 121.5g tris in 1L dH20. For a 5M stock, use 5x as much tris in the same 1L dh20.607.5 g tris into 800ml dH2O - stirring - then pH to 7.5 with 6M HCl and QS to your final volume of 1L
What is the difference between tris and tris hcl?
They are all basically the same thing. Tris-HCl is just the Tris base converted to a salt with HCl. You can buy either one. The advantage of starting with powdered Tris-HCl is that it is more soluble in water than the base and as a solution has a more neutral pH which is usually the desirable buffer point. Tris base has a pKa of over 8 so using Tris-HCl saves you the trouble of bringing it to a more neutral pH. The one thing to be careful of when making solutions from powder is to be sure to use the correct molecular weight which differs between the two. To answer your specific question, it doesn't matter which you start with except in the rare cases where the sodium from the NaOH would be an issue. For your situation where the solution is going to be slightly basic, it sounds like you could use either one as the starting reagent. I would go with whatever is already around the lab.

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.

How do you prepare 0.1M tris HCl buffer of pH 8?
Tris(hydroxymethyl)aminomethane (Tris) has a molecular weight of 121.14 g/mol. 50 mM = 0.050 mol/L (x 121.14 g/mol) = 6.057 g/L To prepare a 1L solution first weigh out 6.057 g Tris Add roughly 70% of final volume of water (i.e. 700 mL) Use a pH-meter to measure the pH of the solution Lower the pH of the solution to 7.2 using undiluted HCl Use a measuring cylinder or volumetric flask to make the volume up to 1000 mL If you add too much HCl you need to add more Tris and then recalculate the amount of water that you need add. In this case, every 1 g of Tris requires 165 mL of water to be added.

What are plasmid genes?
A plasmid is an extra chromosomal DNA molecule separate from the chromosomal DNA which is capable of replicating independently from the chromosomal DNA http://en.wikipedia.org/wiki/Plasmid I think this is far use.
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.
