How do restriction enzymes identify introns that are to be cut from mRNA before protein synthesis?

We have been reasearching DNA, DNA replication, and protein synthesis.  We have learned that 
restriction enzymes are sometimes signaled with certain coding sequenes in nucleic acids, such as the 
sequene A-A-G-C-T-T.  but this sequence is in DNA form (using thymine, not uracil) and we are not 
sure that there are restriction enzyme coding sequences in RNA.  We would much appreciate your 
help on this subject.
Thank you for your time, we hope you can find an answer to our question.
