WebRNA splicing. RNA splicing is a process in molecular biology where a newly-made precursor messenger RNA (pre- mRNA) transcript is transformed into a mature messenger RNA ( mRNA ). It works by … Eukaryotic genomes contain large numbers of splice sites, known as cryptic splice sites (css), which are generally held to be disadvantageous sites that are dormant or used only at low levels unless activated by mutation of nearby authentic or advantageous splice sites (1,2). Once activated, css may be used … See more The CSF program is designed to identify transcripts that are generated through the low level use of css by normal genes. In addition, CSF also identifies a subset of alternative splice sites that are similar to css, but are used at … See more Reserch grants from Biotechnology and Biosciences Research Council and Atazoa.
