Origin and Evolution of Life
Electric discharges can generate organic molecules
The Murchisonmeteorite containsorganic moleculese.g. D- and L-amino acids
Ribozymes and introns may be relics of an RNA world
Peptide bond formation in ribosomes
Directed evolution:Artificial RNAs can polymerize ribonucleotides in vitro
Primordial replicases:RNAs may catalyze its own replication
A putative RNA replicase cycle
No Darwinian evolution outside of compartments
Compartmentalization may lead to accumulationof improved RNA replicases
A synthetic minimal genome
Living bacteria that harbor a synthetic minimal genome
