When working with RNA it’s acceptable to use ddH2O to make solutions so long as all instruments coming in contact with the product are certified nuclease-free or autoclaved.

When using organic solvents to extract RNA, the RNA fraction will be found where after centrifugation?

After weighing the masses of Tris and EDTA you calculated in the previous question, you dumped the powders in a standard lab beaker, added ddH2O to the 100mL mark on the beaker and stirred until the powder was completely dissolved. Is this solution correctly made and ready for use as described (yes or no)? Justify your answer.

You need to make 100mL of TE pH 8.0 buffer (consisting of 120mM Tris and 1mM EDTA) for a DNA extraction. You have Tris base powder and EDTA powder from which to make it. Tris powder has a MW of 121g/mol, while EDTA powder has a MW of 292g/ml. [Answer 1] How much Tris powder will you need for this desired volume of TE solution? [Answer 2] How much EDTA powder will you need?
