In Search of Unintentional Truth,be approximated by the terms mafic (basaltic) for ocean crust and felsic (granitic) for continental crust. Oceanic crust is thin (ca. 10 km) and relatively dense while continental crust is rather thicker (ca. 40 km) and somewhat less dense. Both types “float” on the solid, higher density mantle of u

A Diary of the Euro Crisis in Cyprusious types of RNA, and polypeptides that comprise most of the catalysts controlling the rates of various biochemical reactions essential to maintaining life. DNA is the site of storage of the genetic information, coded as sequences of a small number of nucleotide monomers attached to one another in

Attempts to obtain useful amounts and types of prebiotic compounds starting from these more oxidized conditions typically require some method to

resence of a catalytic feedback loop linked to an information storage system. The catalytic feedback results in production of life components and replication of the information storage system, implying both “organismal” growth and (re)production of offspring. The DNA-RNA-protein system of extant lif

A Dictionary of Earth Sciences,sted, 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
