Why does ribosomes use rna instead of dna?

After some “pre-processing” inside the nucleus, the much shorter mRNA molecule (compared to the DNA chromosomes) is transferred from the nucleus to the cell cytosol, where a ribosome (aided by transfer RNA (tRNA)) performs the translation from mRNA to a protein (or, as the case may be, to another RNA) molecule.

the generally accepted parts of modern cell theory include: all known living things are made up of one or more cells. all living cells arise from pre-existing cells by division. the cell is the fundamental unit of structure and function in all living organisms.
