Indian-origin scientist discovers how life took shape on earth

An Indian origin scientist Ramanarayanan Krishnamurthy from Scripps Research in California has discovered a fresh explanation as to how life took shape first time on the earth.

He has discovered that a mix of RNA-DNA was responsible for the beginning of life on earth.

According to him, the dithiophosphate (DAP) led to the formation of life on the earth. A chemical reaction could have assembled deoxynucleosides into strands of primordial DNA. The process may have taken place before any form of life.

Published in a chemistry journal Angewandte Chemie, his study into the matter is the latest in the series of discoveries that point to the possibility that both DNA and RNA are the result of similar chemical reactions.

“This finding is an important step toward the development of a detailed chemical model of how the first life forms originated on Earth,” said study senior author Krishnamurthy.

“Now that we understand better how a primordial chemistry could have made the first RNAs and DNAs, we can start using it on mixes of ribonucleoside and deoxynucleoside building blocks to see what chimeric molecules are formed–and whether they can self-replicate and evolve,” Krishnamurthy elaborated.
