1 micron is 10,000 angstroms
very very far off Nucleus is of the order of fermi (10-15 m.).And atom is of the order of angstorm A (10-10 m.).Now you realise
venkatraman Ramakrishnan's laboratory published 5.5 angstorm resolution structure of 30s sub units.later, they determined the complete molecular structure of 30s subunits along with some "ANTIBIOTICS" present in it.More recently, they determined the atomic structure of ribosomes in complex along with its tRNA and mRNA ligands.
