Fig. 3. Summary of ray rescue experiments: part I. All transgenic animals were analyzed in the strain CB3531 carrying the null allele Cel-mab-5(e1290), which forms no V-rays. At least three transgenic lines were tested for each construct. Black rectangles, coding exons; stippled rectangles, introduced frame-shift mutation; X, the unique restriction site in pAG2 and all further constructs. Inserted cDNAs in pAG4 and pAG5 are indicated. n, number of animals analyzed.
