Each snRNP contains a single snRNA (100-300 nt) and several (20) proteins. The U4 and U6 snRNPs are usually found together as a di-snRNP (U4/U6) particle.

Once DNA has been melted, the trajectory of the individual strands within the enzyme is no longer constrained by the rigidity of the double helix, allowing DNA to make its 90° turn at the active site.

There are RNA polymerase crystal structures that provide considerable insight into how the enzyme retains contact with its substrate while breaking and remaking bonds in the process of the nucleotide addition cycle and undergoing translocation by a Brownian ratchet mechanism.
