A suggested pioneer organism for the Wächtershäuser origin of life hypothesis.

Abstract A suggested pioneer organism for the Wächtershäuser origin of life hypothesis is presented. In this scenario, a cubic pyrite crystal edge serves as a catalytic surface for the production of a proto-nucleic acid. Computational analysis demonstrates how the vacant cubic pyrite edge could be populated by iron(II) and hydrogen phosphate, capped with a distorted iron pentacarbonyl. A bridging iron sulfide then forms blocking one side of the edge. The carbonyl on the other side of the edge can then react with either existing uracil or cytosine, to produce a nitrogen-iron carbonyl intermediate. This intermediate serves as a free radical initiator for a polymerization of carbon monoxide and molecular hydrogen. After the fourth carbon is added to the chain, the polymerization is terminated by ring formation yielding a condensed ribose. The resultant product is a proto-nucleic acid, a pioneer organism.

About National Digital Library of India (NDLI)
NDLI logo

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
