[Interaction of tRNA with ribosomes].
Definition of the site of tRNA-binding to ribosomes is suggested on the basis of a free energy of tRNA-ribosome interaction. From this point of view disagreements that have arisen in recent years concerning the numbers of tRNA binding sites on the ribosome, their distribution between subunits, the properties of the third site E in ribosomes and the compatibility of new experimental data with different models of elongation cycle are discussed. The observation of the third site in the ribosome (messenger independent and with a presumably exit function) is not a refutation but an extension of Watson's model of translating ribosome.
