In 1958 Crick proposed that the information present in DNA (in the form of base sequences) is transferred to RNA (the process is called transcription) and then from RNA it is transferred to proteins in the form of amino-acid sequence (called translation) and that this information does not flow in the reverse direction i.e. from protein to RNA to DNA. This relationship between DNA, RNA and protein is known as central dogma.
