Precursor 16S RNA in Active 30S Ribosomes
Copyright policy )Precursor 16S RNA in Active 30S Ribosomes
BIOGENESIS of bacterial ribosomes proceeds through the formation of precursor particles1–4, consisting of an incomplete set of ribosomal protein5 and of RNA molecules that are longer and less methylated than mature RNA4,6,7. RNA maturation is commonly considered to be a part of the ribosome maturation process. Here we report that newly formed 30S ribosomes can enter polyribosomes while they still contain precursor RNA. Maturation of ribosomal RNA might be completed not before, but after, ribosomes have interacted with messenger RNA.
