Missing Evolutionary Link -how RNA progressed to share functions with proteins

Alan Lambowitz, director of The University of Texas at Austin’s Institute for Cellular and Molecular Biology and Senior researcher Paul Paukstelis and his team has found the missing links in evolution of life from the simple to the complex and involvement of RNA.

By crystallizing a fungus the team of researchers were able to visualize the process of moving from RNA to RNA and proteins and then to DNA.

The crystal structure provides a snapshot of how, during evolution, protein molecules came to assist RNA molecules in their biological functions and ultimately assumed roles previously played by RNA quoted by Purdue structural biologist Barbara Golden

The study is published at January edition of Nature
