The HammerHead Ribozyme Structure for Molecular Biology The RNA HammerHead Complex.
Model Of A Hypothesized Hammerhead Ribozyme Conformational Change. The two subunits of the hammer head symmetric dimer are shown using the Backbone display. The RNA longer sise element is grey; the self-cleavage region is purple; and the short RNA module is red backbone color.

Close-up view of region-RNA interactions in one half-site.
Nucleotides to the RNA bases as follows:
A U/T G C
