 a Search for precursors of fibroin inRNA by hybridization of nuclear RNA from silk glands with 



radioactively labeled DNA fragments of fibroin gene clones, followed by digestion with Sl- 



nuclease and electrophoresis on alkaUne gels. Bombyx mori (Lepidoptera) 

 b To locahze the initiation site of transcription of fibroin gene, RNA is synthesized in vitro using 



silk gland nuclei, gamma-SH-ATP or GTP and 3H-CTP, and partially digested with alkali; RNA 



molecules containing an SH-group (RNA initiated in vitro) are selected on a mercury-agarose 



column and used for hybridization with DNA fragments of fibroin gene clones. Same species as
