Recall that dilution factors can be used with concentrations of solutions as well as with titers of cell suspensions. a molecular biologist sets up a pcr reaction containing 5.0 µl of primer mixture, 1.0 µl of dntps, 1.0 µl of taq polymerase, 10.0 µl of 5x buffer, 20.0 µl of extracted dna solution, 3.0 µl of 25 mm mgcl2 and 10.0 µl of sterile water. what would be the final concentration in mm of mgcl2 after the components are mixed?

Approximately percent of the energy created by cell metabolism is used by the body to carry on its normal functions, such as respiration, digestion, reproduction, muscular movement, circulation, and cellular regrowth.
