When proteins are needed, the corresponding genes are transcribed into RNA (transcription). The RNA is first processed so that non-coding parts are removed (processing) and is then transported out of the nucleus (transport).

RNA (ribonucleic acid) is an information encoded strand of nucleotides, similar to DNA, but with a slightly different chemical structure. There are three main forms of RNA, each a slightly different function.

RNA: Ribonucleic acid. Single-stranded where DNA is double-stranded, messenger RNA carries single pages of instructions out of the nucleus to places they're needed throughout the cell. No error detection or repair; ... Transfer RNA helps translate the mRNA message into chains of amino acids in the ribosomes. [Diagram of RNA...

Ribonucleic acid or RNA is a nucleic acid polymer consisting of nucleotide monomers that plays several important roles in the processes that translate genetic information from deoxyribonucleic acid (DNA) into protein products; ... RNA acts as a messenger between DNA and the protein synthesis complexes known as ribosomes,

RNA folding ... RNA is transcribed (or synthesized) in cells as single strands of (ribose) nucleic acids. However, these sequences are not simply long strands of nucleotides. Rather, intra-strand base pairing will produce structures such as the one shown below.

The structural difference with DNA is that RNA contains a -OH group both at the 2' and 3' position of the ribose ring, whereas DNA (which stands, in fact, for deoxy-RNA) lacks such a hydroxy group at the 2' position of the ribose.
