What is the function of RNA in living systems?

Step-by-step solution

Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are the two types of nucleic acids found in living systems. DNA acts as the genetic material in most of the organisms. RNA though it also acts as a genetic material in some viruses, mostly functions as a messenger. RNA has additional roles as well. It functions as an adapter, structurally, and in some cases as a catalytic molecule. It functions as adapter, structural, and in some cases as a catalytic molecule.
