in the male rat kangaroo cell line ptk2 , argon laser ( 514.5 nm ) microirradiation of both nucleoli in interphase cells 30 , 23 , and 12 h before mitosis , and nucleoli in early prophase cells resulted in the formation of micronucleoli , i.e. , several small nucleolus-like bodies , in daughter cells .
