This is supported by widespread similarities within information processing machinery [10].
From the standpoint of the genome sequence comparisons, eukaryotes are genetic chimaeras with archaebacterial type ribosomes in the cytosol, a largely archaebacterial-type information processing machinery and eubacterial-type energy production and metabolic machinery.
We believe that eukaryotes and archaea are sisters because we believe that the genes that produce this sisterhood relationship, which are mostly those of translation and other components of the information processing machinery, tell the true story of eukaryote origins.
Being part of the information processing machinery of the cell, the gene for S4 is generally thought of as being inherited vertically and has been used in concatenated gene phylogenies.
In other words the genetic information stored in XNA is invisible to the information-processing machineries of natural cells and therefore useless to DNA-based organisms.
Due to the evolutionary conservation of information-processing machineries between Archaea and Eukarya, archaeal and eukaryotic nucleic acids motors are also more closely related to each other than to bacterial counterparts.
This is reflected by the conservation of information-processing machineries in Archaea and Eukarya, including molecular machineries of chromosome replication, DNA damage repair, gene transcription and protein translation [ 4, 5].
The research team, led by Seth Grant of the Sanger Institute near Cambridge, England, compiled the first exact inventory of all the protein components of the synaptic information-processing machinery.
This will in turn modify future processing of sensory stimuli and ultimately lead to an altered architecture of the brain's processing machinery and information processing modes.
Therefore, controversy still surrounds the fundamental and largely unanswered question of whether NATs participate in biologically significant information processing and regulation of macromolecular machineries.
