Making proteins by translating messenger RNA. The DNA helix opens up. Messenger RNA, or DNA fragment, made up of a sequence of ordered bases called sequences, combines from a strands of the helix (transcribed strand). It is the transcription. It leaves the nucleus through its ports, passes into the ribosomes which decipher them by batch of 3 successive bases (codon) each giving an amino acid which recombined will give a protein. It is the translation.
