the presence of histone encoding regions in the lambda hhg clones was demonstrated by several independent criteria including hybridization with specific dna probes , hybrid selection/in vitro translation , and hybridization of lambda hhg dnas to reserve southern blots containing cytoplasmic rnas from g1- , s- , and arabinofuranosylcytosine ( cytosine arabinoside ) -treated s-phase cells .
