Is there any other Genetic Material in this world.. Other than DNA & RNA?
All currently known genetic material is either DNA or one of the many forms of RNA. You’re probably referring to the Murchison meteorite which hit Australia in 1969. Nucleotides were found, and testing showed that they contained a a higher ratio of carbon-13 atoms than nucleotides found in the surrounding soil, suggesting they originated in space. The chemical processes which create organic molecules are by no means unique to Earth, and they can be formed by some pretty basic processes (see the Miller-Urey experiment), so it is likely that organic molecules, if not self-replicating molecules, would be fairly common throughout the universe. There’s no scientific reason that DNA and RNA should be the only molecules able to store information as a genetic sequence, other than their relative stability, so there could well be some exotic form of genetic material that we’ve yet to discover.
