Ribonucleic acid, also known as RNA, is found almost exclusively in the cytoplasm of cells, although at times it can created in the nucleus of the cell. RNA is a major biological macromolecule that is required for life.
Along with RNA, DNA and proteins are also required for life. DNA, or deoxyribonucleic acid, is composed of the genetic information of a cell that determines how it behaves, maintains itself and grows. RNA is created as a copy of certain parts of the DNA. The RNA is then used by another component of cells, ribosomes as a set of instructions for what proteins should be made to accomplish a certain task.
