Based on its definition, the luminous intensity (cd) is not a base quantity (unit), therefore it is moved to the list of derived quantities (units). The ampere and coulomb are exchanged by places in the list of base and derived units, as ampere is a speed of coulombs (but SI ...

The phosphodiester of the DNA backbone has a formal electrostatic charge of a^{-1} What is the work required to assemble two single helical strands of DNA (each with 5 bases) into a double helix? Assume a Coulomb constant of unity. Is the sign of the wor ...
(at 56 °C for 30 min), 100 units/ml of penicillin, and 2 mg/mL of streptomycin. Cell harvesting employed trypsin (0.25 X 10−1% w/v), while unbound sulforhodamine B (SRB) dye was dissolved using acetic acid (1% v/v). The protein–dye SRB (0.40%) was dissolved in 1% acetic ...
