For 10 points, name this substance that has ribosomal, messenger, and transfer types, and is a macromolecule contrasted with DNA.
Interferon defense is sometimes activated by the "small hairpin" type of this substance, a variant that is similar to the "small interfering" type which leads to a namesake "interference." This substance's introns are cut by (*) spliceosomes, which are formed by snRNPs [pr. snirps]. This molecule follows a 5 prime to 3 prime direction and replaces the pyrimidine thymine with uracil.
