Measurements of the amount of dna per nucleus were taken on a large number of cells from a growing fungus. the measured dna levels ranged from 3 to 6 picograms per nucleus. in which stage of the cell cycle did the nucleus contain 6 picograms of dna?

Large electric fields in cell membranes cause ions to move through the cell wall. the field strength in a typical membrane is 1.0 x 10 7 n/c. what is the magnitude of the force on a calcium ion with charge +e? what is its acceleration? is it possible for a particle with the same charge as as calcium to have a different acceleration if placed at this location? what would change the acceleration: mass of the particle? diameter of the particle?
