(5 µg)(1000 ng/µL)(x µL / 91.6 ng) = _____ µL
Concentration from Nanodrop = 91.6 ng/µL
The amount of 10X DNase I reaction buffer for 100ul of reaction may be calculated as follows:
For 1ul 10X DNase I reaction buffer, 10units of buffer is present
For 100ul reaction volume, the amount of 10X DNase I reaction buffer needed will be= 100units/10X=10ul
Hence 10ul of 10X DNase I reaction buffer is to be added to a 100ul reaction volume.
Concentration of RNA from Nanodrop=91.6ng/ul
Needed concentration of RNA to add in the reaction is 5000ng (5ug)
The volume of RNA needed to be added will be:
1ul of RNA = 91.6ng
?ul of RNA= 5000ng
=> 1*5000/91.6=54.58ul of RNA needs to be added in the reaction to make it to a final concentration of 5000ng.
The amount of RNase free water added will be the amount required to make up to 100ul after adding RNA and 10X DNase I reaction buffer
Hence the reaction will contain the following amounts of each component:
RNA=54.58ul
10X DNaseI reaction buffer= 10ul
RNase free water=35.42ul
Total reaction volume=100ul
If you have any query kindly comment before giving thumbs up. Thank you.

Question 6 Using stock solutions to make up a solution: from final concentration to volume You need to digest a sample of DNA with a restriction enzyme. You will do this reaction later in the semester. The buffer for this reaction has a final concentration of 40 mM Tris, pH 7.5, 10 mM MgCl2 and 50 mM KCl. You have the following stock solutions: 0.5 M Tris, pH 7.5, 1 M MgCl2 and 2 M KCl. How would you make...
You are preparing to clone a DNA fragment into a plasmid vector. You start by linearizing your plasmid (concentration = 500 ng/μl) with EcoRI, which is provided in a standard 50% glycerol solution at 10 units/μl. Your enzyme also comes with an appropriate 10X reaction buffer. Taking into account the final allowable glycerol concentration, you want to add the maximum amount of EcoRI, to achieve complete digestion of 1 μg plasmid DNA in a total volume of 20 μl. Fill...
Question 5 Using stock solutions in a protocol: from volume to final concentration A reverse transcription reaction is carried out in a 30 μL reaction mix. This type of reaction is carried out to convert RNA to complementary DNA. You are going to set up a number of these reactions so you decide to make up a larger volume of the reaction mixture, called a master mix. This saves on multiple repetitive pipetting and reduces errors. You have been given...

Your lab instructor has given you a protocol to perform a molecular cloning experiment. In a previous experiment, you used polymerase chain reaction (PCR) to amplify a sequence that you believe to regulate expression of a gene you are studying. You will now take this purified PCR product (double stranded DNA) and ligate it into a plasmid that contains a luciferase reporter gene. If your DNA sequence is a promoter sequence, then its presence will allow for expression of the...

please , i need Write the protocol by your own words ( steeps) 5. Add 1 volume of 70% ethanol to the cleared lysate, and mix immediately by pipetting. Do not centrifuge. Proceed immediately to step 6. Note: The volume of lysate may be less than 350 pl or 600 pl due to loss during homogenization and centrifugation in steps 3 and 4. Note: Precipitates may be visible after addition of ethanol. This does not affect the procedure. 6. Transfer...
