The chemical origins of molecular biology

Lead Research Organisation: MRC Laboratory of Molecular Biology

Abstract

An English chemist has found the hidden gateway to the RNA world, the chemical milieu from which the first forms of life are thought to have emerged on earth some 3.8 billion years ago. He has solved a problem that for 20 years has thwarted researchers trying to understand the origin of life — how the building blocks of RNA, called nucleotides, could have spontaneously assembled themselves in the conditions of the primitive earth. The discovery, if correct, should set researchers on the right track to solving many other mysteries about the origin of life. It will also mean that for the first time a plausible explanation exists for how an information-carrying biological molecule could have emerged through natural processes from chemicals on the primitive earth.

Technical Summary

A true understanding of biology must include knowledge of its chemical origin, and comprehending the chemical events that gave biology its foundations – cellular format, the central dogma, the genetic code – is therefore a fundamental aspect of natural science. Furthermore, understanding the way in which extant biology arose can inform the design of synthetic biologies. We are interested in using the tools of organic chemistry (synthesis and analysis) to uncover prebiotically plausible syntheses of the informational, catalytic and compartment–forming molecules necessary for the emergence of life. We have previously demonstrated the constitutional self-assembly of pyrimidine ribonucleotides from mixtures of simple building blocks, and we are now exploring similar systems chemistry approaches to the purine ribonucleotides, and ways of assembling RNA from these ribonucleotides with regiocontrol of the internucleotide phosphodiester linkage. We are also interested in the chemical origins of genetically encoded translation, and the abiogenesis of lipids.
