Transformation efficiency = (Total number of cells growing on the agar plate) / (Amount of DNA spread on the agar plate (in µg)).
So if the transformation efficiency is 4 x 10^3 and the amount of plasmid on the plate is 0.04 micrograms, then:
4 x 10^3 = x / 0.04 micrograms, so x = 160 colonies.
So if the transformation efficiency is 4 x 10^3 and the amount of plasmid on the plate is 0.04 micrograms, then:
4 x 10^3 = x / 0.04 micrograms, so x = 160 colonies.
