On the dimerization of the primitive tRNAs: implications in the origin of genetic code.

A structural model for the first aminoacyl-tRNA synthetase consisting of an RNA complex formed between two primitive tRNA molecules through two intermolecular loop-strand interactions is proposed, with implications in the origin of the genetic code.

RNA evolution and the origins of life

It is doubtful that life began with RNA, but consideration of what came before RNA must take into account relevant information from geochemistry, prebiotic chemistry and nucleic acid biochemistry.

Pioneering role of RNA in the early evolution of life

The catalytic, regulatory and structural properties of RNA are consistent with the proposal that this molecule played a much more conspicuous role in heredity and metabolism during the early stages of biological evolution.

Catalytic activity of an RNA molecule prepared by transcription in vitro.

The RNA moiety M1RNA of ribonuclease P from Escherichia coli and the unprocessed transcript prepared in vitro of the gene for M1 RNA can both perform the cleavage reactions of the canonical enzyme in the absence of the protein moiety.

The intervening sequence RNA of Tetrahymena is an enzyme.

The shortened form of the self-splicing ribosomal RNA intervening sequence of Tetrahymena thermophila acts as an enzyme in vitro that can act as an RNA polymerase, differing from the protein enzyme in that it uses an internal rather than an external template.
