SUMMARY The polya posterior gives a noninformative Bayesian justification for various single-stage sampling procedures. Here this type of reasoning is extended to two-stage cluster sampling problems. The frequency properties of the resulting procedures are studied.

A growing number of human disorders have been associated with expansions of a tract of a single amino acid. Recently, polyalanine (polyA) tract expansions in the Aristaless-related homeobox (ARX) protein have been identified in a subset of patients with infantile spasms and mental retardation. How alanine expansions in ARX, or any other transcription factor, cause disease have not been determin...

Our previous study has shown that there is a good correlation between the number of charges of DNA (from trimer to 50-mer) and the number of binding sites B in electrostatic interaction chromatography (ion-exchange chromatography, IEC). It was also found that high salt (NaCl) concentration is needed to elute large DNAs (>0.6M). In this paper we further performed experiments with large DNAs (up ...

Proper cellular response to genotoxic insult often requires the activity of one or more members of a family of high-molecular weight protein kinases referred to as phosphatidylinositol-3 kinase (PIK)-like proteins. While catalytic activity is an indispensable part of PIK-like protein function, little is currently known about factors that control their activity and/or functions. This de®ciency s...

To investigate the role of 3' end formation in yeast mRNA export, we replaced the mRNA cleavage and polyadenylation signal with a self-cleaving hammerhead ribozyme element. The resulting RNA is unadenylated and accumulates near its site of synthesis. Nonetheless, a significant fraction of this RNA reaches the cytoplasm. Nuclear accumulation was relieved by insertion of a stretch of DNA-encoded ...
