Model of ribosomal binding to tRNA (IMAGE) University of California - Berkeley Caption The researchers performed molecular dynamics simulations on a model system based on cryo-EM studies of the structure of the E. coli ribosome. The region of the ribosome shown here (blue ribbons and green squiggles) are involved in forming bonds between amino acids or other monomers. The tRNAs (red ribbons) are shown delivering novel monomers (gray spheres) to be incorporated into polymers. Water molecules (red) and ions (blue) surround the structure.
