The third form of life
Article Abstract:
Recent studies have debunked the assumption that there were only two types of primary organisms, namely, the prokaryotes and the eukaryotes. A group of organisms was discovered that exhibited some of the qualities of both types and was named archaeabacteria. Genetic sequence tests conducted on archaeabacteria revealed no major differences with the earlier eubacterial genomes. However, the major difference archaeabacteria have over the two other types is that they possess a mixture of both genetic codes.

An early evolutionary origin for the minor spliceosome
Article Abstract:
The identification of homologoues of minor-spliceosome-specific proteins and small nuclear RNAs (snRNAs), and U12-type (an atypical class of spliceosomal introns), in distantly related eukaryotic microbes (protists) and in a fungus (Rhizopus oryzae) is reported. The results have indicated that the minor spliceosome had an early origin and have revealed marked evolutionary conservation of functionally important sequence elements contained within U12-type introns and snRNAs.
