Central dogma of genetics.

   Genetic  information  is encoded as a sequence of deoxyribonucleotides
   on one of the two strands of DNA (the template strand).

   Transcription  produces  a "messenger" RNA (mRNA) complementary to the
   template.

   Translation occurs on ribosomes in the cytoplasm, where the message on
   mRNA  determines  the  sequence of amino acids that are assembled into
   proteins.
