Select all that apply. The sedimentation coefficient: is obtained when a particle has neutral buoyant density. is affected by the shape of the sedimenting particle. is directly proportional to the molecular weight of a particle in an ultracentrifuge. values are additive, so a 50S ribosome will dissociate to two 25S subunits. is expressed in Svedberg units, named after the scientist who invented the ultracentrifuge.
