| - | <scene='72/726441/Rnascene/1'> | + | Focusing <scene name='72/726441/Rnascene/1'>on the RNAs</scene> reveals secondary structure and extensive base pairing between the U4 and U6 snRNAs. |
| - | The U2 snRNP | + | The spliceosome is assembled from the U4/U6.U5 tri-snRNP, the U1 snRNP, and the U2 snRNP. The U2 snRNP interacts with the region highlighted in blue <scene name='72/726441/Dockscene/1'>in this view</scene>. The U1 snRNP interacts with the U2 snRNP. The initial assembly is inactive; extensive conformational changes (including unwinding of the U4/U6 base pairing) are required for activation of the spliceosome. |

| - | This is a sample scene created with SAT to <scene name="/12/3456/Sample/1">color</scene> by Group, and another to make <scene name="/12/3456/Sample/2">a transparent representation</scene> of the protein. You can make your own scenes on SAT starting from scratch or loading and editing one of these sample scenes. | ||
