We have made a P-element derivative called Pc[ry], which carries the selectable marker gene rosy, but which acts like a nondefective, intact P element. It transposes autonomously into the germline chromosomes of an M-strain Drosophila embryo and it mobilizes in trans the defective P elements of the singed-weak allele. Frameshift mutations introduced into any of the four major open reading frames of the P sequence were each sufficient to eliminate the transposase activity, but none affected… CONTINUE READING
