Question: The average molecular weight of a nucleotide (base + deoxyribose + 1 phosphate group) in DNA is308g/mol of 308 Daltons (Da). This number is the average molecular weight ofA = 312.2 g/molG = 328.2 g/molC = 288.2 g/molT = 303.2 g/mol
a) Which plasmid was used for the transformation experiment? What is the size of this plasmid (in kilo base pairs; kbp)? How many bases is this?
b) What is the molecular weight of one plasmid molecule?
c) You used 25µl of 1ng/µl plasmid DNA per transformation. How many grams of plasmid DNA did you use? How many moles of plasmid DNA is that? How many molecules of plasmid DNA is that?
d) Assuming each transformed cell pick up one plasmid molecules during the transformation process, what percentage of DNA molecules successfully entered and replicated inside the competent cells?
