RNA (ribonucleic acid)

RNA (ribonucleic acid) is a molecule with a structure like DNA, but it has a single strand. It has genetic information copied from DNA. There are different types of RNA in a cell, each with a specific job. These include messenger RNA (mRNA) and transfer RNA (tRNA).

In humans, DNA causes RNA to be formed and carry out messages within the body. In some viruses, RNA is the genetic material rather than DNA.
