DNA and RNA molecules have till now been claimed as the basis for all life on Earth. But researchers’ new discovery claims that they have found some similar molecules to DNA and RNA, which have shown similar potential of exhibiting hallmarks of life as is done by DNA and RNA molecules.
The above findings are coming from the researchers’ team at the Medical Research Council in Cambridge, England. The team of experts showed that not only DNA and RNA have to provide the basis for all life everywhere, but some more molecules can serve the purpose.
In their recent demonstration, researchers highlighted six more synthetic molecules that have found in their latest studies. They claim the molecules to be almost similar to DNA and RNA with same potential to exhibit hallmarks of life like capabilities of storing genetic information, passing it along and undergoing evolution. The newly discovered man-made molecules have been named as "XNAs”.
DNA and RNA had been big answers till now for the medical industry. But Mr. Vitor Pinheiro, the postdoctoral researcher who led the above study, cleared in his statement, that they manipulated XNAs to behave like DNA and RNA, which can help scientists majorly to design better drugs for the medical industry. The above findings have been published this week in the journal Science.
Hopes are higher that the new findings will uncover many facts related to emerging of life on Earth or what would had been the existence structure of living things beyond our planet as few researchers believe life has existed from RNA molecules.
"Everyone wants to know what aliens would use for DNA”, said Steven Benner, a biochemist at the Foundation for Applied Molecular Evolution in Gainesville, Fla., who has synthesized artificial DNA but was not involved in the new study. "Lab experiments tell you about the possibilities in the universe”.
