The living features of cells constitute an information flow from a central database, the nuclear DNA, to molecular effectors, proteins, which are synthesized in the cytoplasm. This flow comprises two changes in information units: transcription and translation. Transcription is carried out in the nucleus and consists on the transduction of specific instructions from the DNA to an intermediary, the RNA, which in its canonical form is a messenger (mRNA) that takes out information from the cell nucleus. In the cytoplasm, information of the messenger gives the commands for a specialized molecular complex to build a specific protein. After conformation regulation, proteins are integrated as structural and/or functional units in the complex network of biological functions in the cell.
