The structure activity relationship was the primordial notion upon which the authors' studies are based.
Working with a script that he co-wrote with Gilles Taurand, Ruiz turns the play of the author's memory into a primordial Surrealism by way of bold visual analogies and sonic associations akin to rhymes.
A general problem with models of primordial evolution, not to be held against the authors.
The authors conclude that glycine was the primordial tRNA, produced by hairpin duplication, and that other specificities arose from this original activity.
Using computer simulations, the authors show that protocells containing such primordial chromosomes can survive if both circularization and sufficiently high self-cleavage activity are assumed.
She quotes from a poem of his: Suddenly I am raised aloft by primordial passion; I become Leader, Law, Light, Prophet, Father, Author, and Journey, Rising above this world to the others that shine in their splendor.

The phylogenetic analysis also led the authors to conclude that PF13_0289 is a primordial ancestor (termed a "metacaspase") of the caspase family in multicellular organisms (Wu et al. 2003; Meslin et al. 2007), which would explain the limited similarity identified with homology methods.
Further, since there are several minerals with this capacity, different authors advocated participation of different minerals in the primordial (photo)syntheses.
Reviewer 1: Paul Higgs, McMaster University, nominated by Arcady Mushegian Comments on 'Exceptional error minimization in putative primordial genetic codes' At the beginning of this paper, the authors note that numerous hypotheses have been formulated regarding the genetic code but no generally accepted consensus has been reached.
