▪ Abstract Genome sequences of a number of archaea have revealed an apparent paradox
in the phylogenies of the bacteria, archaea, and eukarya, as well as an intriguing set of …

Since most archaea are extremophilic and difficult to cultivate, our current knowledge of their
biology is confined largely to comparative genomics and biochemistry. Haloferax volcanii …

The Z-curve is a three-dimensional curve that constitutes a unique representation of a DNA
sequence, ie, both the Z-curve and the given DNA sequence can be uniquely reconstructed …

The hyperthermophilic euryarchaeon Pyrococcus abyssi and the related species
Pyrococcus furiosus and Pyrococcus horikoshii, whose genomes have been completely …

Maintenance of the information embedded in the genomic DNA sequence is essential for
life. DNA polymerases play pivotal roles in the complex physiological processes of DNA …

Although DNA replication is the universal process for the transmission of genetic information
in all living organisms, until very recently evidence was lacking for a related structure and …

The heterogeneity of gene nucleotide content in prokaryotic genomes is commonly
interpreted as the result of three main phenomena:(1) genes undergo different selection …

Whereas the process of DNA replication is fundamentally conserved in the three domains of
life, the archaeal system is closer to that of eukarya than bacteria. In the time since the …

We analysed chromosome replication patterns in the two hyperthermophilic euryarchaea
Archaeoglobus fulgidus and Methanocaldococcus (Methanococcus) jannaschii by marker …

Homologous recombination is a fundamental cellular process that rearranges genes both
within and between chromosomes, promotes repair of damaged DNA and underpins …
