The problems with trying to piece together a plausible mechanism for the origin of life multiply up.

Scientists also have envisage a scheme that explains the origin of the whole system of genetic information with its unique language, replicating systems, translation devices.
This video provides a great animated version of what some of that entails. Looks like Lego DNA to me!
