5 5. Fill in the table below to set up the reactions for a single and then a set of PCR reactions: Concentration in Volume in 1 Master Mix for four Reagent Stock concentration 10X 25 mM one reaction 1X 2 mM reaction 25 jl reactions Buffer MgClz dNTPs Primer mix DNA template Taq polymerase water Total volume 2.SA 2 al 2.S A Pe 100 nM-0.IA 2 ng/HI 1 unit VS 10 μΜ 0.25 l 100 ng/ul NIA units/ μ1 0.2 - 7.05 82.25 25 ul 25 ul to account for pipetting error we recommend you plan for at least one extra reaction 6. To make individual reactions you would add DNA 10 master mix to of the template

Answer #1

Answer. 6 as given that in one reaction 0.50 ul of template DNA is used. So for 5 reaction 0.50 × 5 = 2.5 ul of template DNA used. Also Total mix is 25 ul then for 5 reaction it will be 25 × 5 = 125 ul.

Also master mix (without template for 1 reaction ) is 24.5 up and master mix for 5 reaction = 122.5 ul.

So, To make individual reactions you would add 24.5 ul master mix to 0.50 ul of the template DNA.

Also for making 5 reaxtion you would add 122.5 ul master mix to 2.5 ul of the template DNA.

    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...
