The mosaic nature of the eukaryotic nucleus.

The phylogenies for each of the protein-coding genes from the Methanococcus jannaschii genome were surveyed to determine the history of the major groups of life, and results indicate that support for the early history of life is not unequivocal.

Respiratory Chains in the Last Common Ancestor of Living Organisms

Molecular data indicate that several of the most important respiratory pathways arose early in evolution and that the last common ancestor of living organisms was not a simple organism in its energetic metabolism and may have been prepared to face a wide range of environmental conditions.

Using the sequences of all the known transcription-associated proteins from Bacteria and Eucarya, it is established that the archaeal transcription system has retained more ancestral characteristics than have the transcription mechanisms in either of the other two domains.

The balance of driving forces during genome evolution in prokaryotes.

The results indicate that the majority of protein families have only been transmitted by vertical inheritance, and it is suggested that gene gain and gene loss in prokaryotes are balanced; thus, on average, prokarian genome size is kept constant.

Comparative Genomics of Mycoplasma: Analysis of Conserved Essential Genes and Diversity of the Pan-Genome

By analyzing the core genome of mycoplasmas, this study finally revealed the conserved essential genes set for myCoplasma survival, and showed that thecore genome set has many characteristics in common with experimentally identified essential genes.

Novel protein families in archaean genomes.

It is shown that the putative laminin receptor family of eukaryotes and an archaean homologue belong to the previously characterized ribosomal protein family S2 from eubacteria, suggesting that archaea seem to have a mode of expression of genetic information rather similar to eUKaryotes, while eub bacteria may have proceeded into unique ways of transcription and translation.

The archaebacteria are the closest living prokaryote relatives of the eukaryotes and are given the formal name Archaea to discourage the common but seldom-voiced opinion that these organisms are really, all things considered, just funny bacteria growing in strange places.

Transcription in archaea: similarity to that in eucarya.

The sequences of the Sulfolobus acidocaldarius subunits D, E, and N and alignments with eucaryal homologs are presented and shows that the archaeal and eucARYal transcription systems are truly homologous and that they differ structurally and functionally from the bacterial transcription machinery.

The role of the rRNAs and some of the insights that have been gained from them are reviewed, and the importance of comparing results from multiple molecules is stressed as a method for testing the overall reliability of the organismal phylogeny.

The Y‐box proteins are the most evolutionarily conserved nucleic acid binding proteins yet defined in bacteria, plants and animals and range from the control of the E. coli cold‐shock stress response to the translational masking of messenger RNA in vertebrate gametes.
