During the sexual cycle of the ciliate Paramecium, assembly of the somatic genome includes the precise excision of tens of thousands of short, non-coding germline sequences (Internal Eliminated Sequences or IESs), each one flanked by two TA dinucleotides. It has been reported previously that these genome rearrangements are initiated by the introduction of(More)
In this study, we compare the effects of three mRNAs-goosecoid, activin and Xwnt-8- that are able to induce partial or complete secondary axes when injected into Xenopus embryos. Xwnt-8 injection produces complete secondary axes including head structures whereas activin and goosecoid injection produce partial secondary axes at high frequency that lack head(More)

summary: From at least as early as Varro, Roman scholars and grammarians occupy themselves with cataloguing peculiar instances of grammatical gender. The practice, with little extant precedent in Greek tradition, finds the grammarians consistently placing great importance upon the identification of grammatical gender with biological sex. I attempt to(More)
