Cytochemical data are presented to show that the histone fractions f1 and f2a are involved in the induction of chromosomal G bands, whereas the f2b and f3 fractions are not involved. Removal of the f1 and f2a fractions probably occurs during fixation and is necessary for the induction of G bands.
细胞化学数据表明，组蛋白组分f1和f2a参与染色体G带的诱导，而f2b和f3组分则不参与。f1和f2a组分的去除可能发生在固定过程中，并且是诱导G带所必需的。
