DNA sequences required for specific and efficient initiation of transcription at the polyoma virus early promoter.

abstract：:Rats and mice have two, equally expressed, nonallelic genes encoding preproinsulin (genes I and II). Cytological hybridization with metaphase chromosomes indicated that both genes reside on rat chromosome I but are approximately 100,000 kilobases apart. In mice the two genes reside on two different chromosomes. DNA se...
