You will use 1.00microgram of each plasmid in a given transformation reaction. The plasmids are at the concentrations listed below. For each of the six different plasmids, how many microliters equals 1.00 micrograms?

#115: .910mg/ml

#138: .558mg/ml

#168: .918mg/ml

#140: .668mg/ml

#81: .430mg/ml

#51: 1.385mg/ml

Answer #1

#115:    910ug ------------ 1ul

           1 ug -------------- 1 X 1 / 0.910 = 1.09 ul

#138: .558ug ------------ 1 ul

             1 ug ------------ 1 X 1 / 0.558 = 1.79 ul

#168: .918mg/ml

              .918ug ------------ 1ul

             1 ug ------------ 1 X 1 / 0.918 = 1.08 ul

#140: .668mg/ml

               .668ug ------------ 1ul

               1 ug ------------ 1 X 1 / 0.668 = 1.49 ul

#81: .430mg/ml

                .430ug ------------ 1ul

                1 ug ------------ 1 X 1 / 0.430 = 2.32 ul

#51: 1.385mg/ml

                  1.385ug ------------ 1ul

                 1 ug ------------ 1 X 1 / 1.385 = 0.72 ul

    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...

    The starting concentration of the plasmid DNA is 100 ngul and you added 2μ1 to your cells. The cells were diluted to one ml prior to plating. First, determine how many transformants you would have if you plated the entire 1 ml of cell:s. Remember, you only plated half or your transformation reaction on plates 1 and 2. Add the number of transformants on plates 1 and 2, and then multiply by 2 for the total number transformants. Record that...

    Cloning / Subcloning When subcloning engineering new plasmids, by inserting new DNA fragments (inserts) me plasmids (now called a vector because it will carry your gene of interest) it is important to considering existing genes / DNA elements. If a site is in the middle of a gene, you could lose or destroy that gene. If there are multiple sites for an enzyme, when you paste them together, multiple possible outcomes can arise. This is undesirable, because it confounds verification...
