Figure 1. Expression of mRNAs for UNC-60A and UNC-60B during C. elegans development. 25 ug of total RNA from the indicated stages was loaded on each lane and probed with radiolabeled cDNAs for unc-60A, unc-60B or 18S rRNA. Samples are embryos (lane 1), L1 larvae (lane 2), L2 larvae (lane 3), L3 larvae (lane 4), L4 larvae (lane 5), young adults (lane 6) and gravid adults (lane 7).

FIGURE 5. Transcript levels of unc-7 vary over the course of development. RNA was isolated from eggs (lane 1). the four larval stages LI (lane 2). L2 (lane 3).L3 (lane 4). and L4 (lane 5),and young adults(lane6). A northern blot containing total RNA, 30pg per lane, was hybridized to unc-7 coding sequences (Ao) r an rRNA probe (B, showing 18s signal). Poly(A)-enriched RNA, 10 ug per lane (C), was hybridized to the same unc-7 probe as in A.
