Validation of suitable internal control genes for expression studies in aging. [PDF]
, 2009 Quantitative data from experiments of gene expression are often normalized through levels of housekeeping genes transcription by assuming that expression of these genes is highly uniform. This practice is being questioned as it becomes increasingly clear

An RNA Conformational Switch Regulates Pre-18S rRNA Cleavage [PDF]
Journal of Molecular Biology, 2011 To produce mature ribosomal RNAs (rRNAs), polycistronic rRNA transcripts are cleaved in an ordered series of events. We have uncovered the molecular basis for the ordering of two essential cleavage steps at the 3'-end of 18S rRNA. Using in vitro and in vivo structure probing, RNA binding and cleavage experiments, and yeast genetics, we demonstrate that

The 5′ end of the 18S rRNA can be positioned from within the mature rRNA [PDF]
RNA, 1999 In yeast, the 5' end of the mature 18S rRNA is generated by endonucleolytic cleavage at site A1, the position of which is specified by two distinct signals. An evolutionarily conserved sequence immediately upstream of the cleavage site has previously been shown to constitute one of these signals.

An integrative description of a population of Mesobiotus radiatus (Pilato, Binda & Catanzaro, 1991) from Kenya [PDF]
, 2018 In a moss sample collected from Mount Kulal in Kenya, a new population of Mesobiotus radiatus was found. Given that the original description of M. radiatus was based solely on the morphology observed by light microscopy and measurements based mostly on a

Phylogeny of protostome worms derived from 18S rRNA sequences. [PDF]
Molecular Biology and Evolution, 1995 The phylogenetic relationships of protostome worms were studied by comparing new complete 18S rRNA sequences of Vestimentifera, Pogonophora, Sipuncula, Echiura, Nemertea, and Annelida with existing 18S rRNA sequences of Mollusca, Arthropoda, Chordata, and Platyhelminthes.
