the collision model can be thought of as a road wide enough for only one car. a smart car is traveling from one direction, and a plough from the other direction, eventually colliding. after the collision, the plough pushes the smart car backwards, as it continues to travel forward. in the collision model for "ube3a/ube3a-ats", rna polymerases (rnaps) travel towards each other along the sense and antisense templates during transcription. the sense and antisense templates overlap for "ube3a" and "ube3a-ats". the two transcription bubbles will collide head-on, and the rnap transcribing the "ube3a-ats", being the plough, will push the rnap transcribing the "ube3a" (smart car), backwards and eventually off of the template. this prevents complete transcription of ube3a.
