title: Question 4: basic questions about the origin of life: on chirobiogenesis.
abstract: Some experimental aspects concerning either the enantio-enrichment of alpha-amino acids starting from non-racemic mixtures or the formation of homochiral oligopeptides and oligonucleotides starting from racemic precursors are described. In principle, it is possible that more than one of these processes had played a role in chirobiogenesis.
