- n. biology Plural form of archaebacterium.
- n. considered ancient life forms that evolved separately from bacteria and blue-green algae
“The authors of the study published in Science noted a number of interesting things - a preponderance of genes encoding protein kinases, evidence for substantial horizontal gene flow from bacteria and archaebacteria, and a streamlined core gene expression machinery transcription and RNA processing.”
“In the neomura theory it was very unlikely that earlier organisms, bacteria, trapped in their non-extremophile yet sturdy protein exoskeleton cell wall, would be able to loose it to develop a new extremophile one (archaebacteria) respectively develop an endoskeleton flexible cell (eukaryotes).”
“Extremophiles as in archaebacteria seems to be the genetically youngest cell type out there at ~ 1 Ga, see Cavalier-Smith.”
“The "community" found in a South Africa deep mine of a single bacterial species loaded with archaebacteria genes and other stuff it has picked up by gene transfer is an exception that comes to mind.”
“Later days DNA has in bacteria and archaebacteria bottlenecked through 70 Celsius, which is roughly the temperature the sediment chert isotopic ratios gives for most of Earth Archaean history.”
“This paper introduced a new domain of life, archae referred to at the time of publication as archaebacteria, and simultaneously created a new paradigm for understanding the origins of life on earth.”
“The discovery and analysis of archaebacteria in the 90s opened us more possibilities.”
“This kind of “horizontal gene transfer” is well documented in the most ancient forms of bacteria that now exist on the planet archaebacteria, and may have provided an opportunity for new properties to be rapidly spread.”
“She then outlined the basis of her theory of the origin of the cell nucleus as a fusion between archaebacteria (thermoplasma) and Eubacteria (Spirochaeta).”
“The biggest break in life, she explained, was between the prokaryotes (cells with nucleoids: monera, prokaryota; archaebacteria, eubacteria) and eukaryotes (cells with nuclei: protoctista, fungi, plantae, animalia).”
Looking for tweets for archaebacteria.
