Understanding the Complex Architecture of the Minor Spliceosome

In human cells, only a small proportion of the information written in genes is used to produce proteins. How does the cell select this information? A large molecular machine called the spliceosome continuously separates the coding and non-coding regions of our genes – and it's doing this even as you read these lines.
