The essence of computation is nonlinearity. A cascade of linear functions, no matter how deep, is just another linear function—the product of any two matrices is just another matrix—so it is ...

The involvement of noncoding mRNAs in many regulatory processes, their abundance, and their diversity of functions has led to the hypothesis that an "RNA world" may have preceded the evolution of ...
