Stephan A. Daubenive. This constraint on which RNA polymers survive and accumulate means that a relatively small amount of nucleotide material is required to synthesize all possible tRNA. This assumes that prebiotic RNA polymerization and duplication is possible, but there are laboratory experiments suggesting just

limate. We compute a high resolution mean dynamical ocean topography (MDT) using geodetic data and derive a detailed model of the global ocean circulation in this crucial area. The MDT is determined using multi-mission altimeter data and the GRACE/GOCE gravity model GOCO2s. The mean sea surface is o

Stephan A. Daubensted, must have acquired this shape for other reasons, the most likely of which would be relative chemical stability. The nucleotide sequence of tRNA allows for multiple base-pairings that result in the peculiar shape of tRNA, but probably also leads to shielding of potential hydrolysis sites by enc

Stephan A. Daubenwater for organisms and ecosystems, including key processes in their cells. It considers successively: the types of water at the Earth’s surface; the sources of the Earth’s water in the Solar System; the different abundances and histories of water on Earth, Venus and Mars; the physical and chemical

Stephan A. Daubento explain that Earth is teeming with organisms and that this has lasted for so long? What makes Earth different from its sister planets Mars and Venus?..The habitability of a planet is its capacity to allow the emergence of organisms. What astronomical and geological conditions concurred to make Ea
