Total RNA was isolated at the indicated time points from synchronized transgenic worms expressing the plet-7B::GFP reporter construct. Levels of endogenous primary let-7 transcripts, transgenic GFP mRNA, mlt-8 mRNA, and 18S rRNA were analyzed by northern blotting. The similar sized B and SL1 transcripts often do not clearly resolve.
