1) RNA. This is the exact description of the RNA. A RNA is a protein derivated from the DNA, which contain a piece of information, like a protein, that need to be built. The Rna take the message to the cytoplasm, where the the protein is built. RNA is equal to DNA, with the difference that the the base U is complementary of the base A, where in the DNA, the complentary base for A is T.
2) Neither dna or rna. An enzim is a protein that act as a cathalist for many reaction. The role of dna and rna is to keep safe the genetic information and make it available on request to produce proteins and enzims, but per se they are not enzim as they do not act like catalist.
