moles dsDNA (mol) = mass of dsDNA (g)/((length of dsDNA (bp) x 617.96 g/mol/bp) + 36.04 g/mol)moles of dsDNA ends = moles dsDNA (mol) x 2DNA
          copy number = moles of dsDNA x 6.022e23 molecules/mol

          mass of dsDNA (g) = moles of dsDNA (mol) x ((length of dsDNA (bp) x 617.96 g/mol/bp) + 36.04 g/mol)

          dsDNA Mass to Moles
          moles dsDNA = mass of dsDNA (g)/molecular weight of dsDNA (g/mol)molecular weight of dsDNA = (number of base pairs of dsDNA x average molecular
          weight of a base pair) + 36.04 g/mol average molecular weight of a base pair = 617.96 g/mol, excluding the water molecule removed during polymerization.
          The 36.04 g/mol accounts for the 2 -OH and 2 -H added back to the ends. Bases are assumed to be unmodified. 

          When a sequence is provided, the exact molecular weight is calculated by summing the molecular weights of the individual nucleotides:dA: 313.23 dT: 304.21
          dG: 329.23 dC: 289.20These weights exclude the water molecule removed during polymerization.36.04 g/mol is added for the 2 -OH and 2 -H added back to
          the ends.

          dsDNA Mass to Moles of Ends
          moles of dsDNA ends = moles linear dsDNA (mol) x 2(see above to calculate moles dsDNA from mass)Bases are assumed to be unmodified.

          dsDNA Mass to Molecules
          number of molecules dsDNA = moles of dsDNA x Avagadro's NumberAvagadro's Number = 6.022e23 molecules/mol(see above to calculate moles dsDNA          
          from mass)
