S. J. Kleinbergists of messenger RNA encoding most of the polypeptides of interest to the vast majority of present day biologists. This mRNA is heterogeneous in size and generally carries long tracts of polyadenylic acid (polyA) at its 3′ end. The mRNA can be purified away from other nucleic acids by hybridization

S. J. Kleinbergmutation prior to DNA sequence analysis. The technique, first described by Fischer and Lerman (.), entails electrophoresis of DNA fragments at high temperature (ca. 60°C) in an acrylamide gel that contains a gradient of denaturant (formamide and urea). As a DNA fragment migrates in the gel, it encou

We believe that people’s expectations of proxemics can be exploited in interaction design to mediate their interactions with devices (phones, tablets, computers, appliances, large displays) contained within
