DNA-Binding Proteins in , Development,tion along the longitudinal axis of the embryo. The generation and diversification of the segments depend on two distinct but integrated processes during early embryogenesis: the subdivision of the embryo into metameric units, and the specification of their identities. Both processes occur simultane

RNA Self-Cleavage by the Hammerhead Structure,(Kruger et al. 1982). Since then, a number of RNA-mediated reactions have been discovered in other systems, including the in vitro RNA self-cleavage reactions that have been extensively characterized in viroid, virusoid and satellite RNAs, in hepatitis delta virus (HDV) RNA and in an RNA transcript

The Mammalian pre-mRNA Splicing Apparatus,rior to the transport of newly synthesized transcripts into the cytoplasm. Splicing is clearly essential, in many eukaryotic transcription units, for the joining together of coding sequences (exons) that are dispersed amongst non-coding regions (introns). In recent years experimental evidence has ac

Interpretation of Experiments that Delineate Transfer RNA Recognition in Vivo and in Vitro, that can be summarized in tabular form as the genetic code. These enzymes recognize a limited set of nucleotide determinants that are necessary and sufficient for attachment of each amino acid to the tRNA bearing the cognate anticodon. The tRNAs are comprised of 74 to 93 nucleotides (76 is the most

The potential role of SMEs includes generating employment and thus contributing to absorbing any labour surpluses which result from economic restructuring; using privatised property for production; contributing to the development of a d
