Abstract:
Sex in the monogenic blowflyChrysomya rufifacies is under the control of a germ-line autonomous maternal effect sex realizer. In order to identify the ovarian poly(A)+RNA that might be related to sex predetermination, we analysed the patterns of cell-free translation products of total poly(A)+RNA from female and male predetermined ovaries and oocytes. During vitellogenesis we observed one transient sex-linked difference in a stable pattern composed of more than 800 in vitro translated proteins. This difference, however, was no longer detectable in mature oocytes.

Ribosomal RNA Synthesis
Ribosome biogenesis begins with the synthesis of 5S and 45S pre-rRNAs by distinct RNA polymerases. The primary transcripts are extensively processed and modified before they are bound and folded by ribosomal proteins and assembly factors,...
