[The role of P-element sequences in the transcription activation]. / Rol' posledovatel'nostei P-élementa v aktivatsii transkriptsii.

ABSTRACT

A study was made of mutations resulting from insertion of the P element in the regulatory region of the yellow gene. Excision of the P element enhanced expression of yellow. Molecular analysis implicated P-element terminal sequences, which remained in the locus after the element was excised, in transcription activation of the yellow gene.
