in order to determine whether this is attributable to some component of the s-phase chromosomal proteins that promotes the transcriptin of histone genes , a component of the g1 phase chromosomal proteins that inhibits histone gene transcription , or both , in the present study chromatin from both g1 and s-phase cells was dissociated and then reconstituted in the presence of various chromosomal proteins .
