Compare and contrast transcription and translation in terms of their purpose and location.

The purpose of transcription is to turn the genetic code found in DNA into RNA. In eukaryotes transcription takes place in the nucleus. After transcription, RNA exits the nucleus to find a ribosome in the cytosol where it codes during translation. In prokaryotes, transcription and translation both take place in the cytosol. Translation involves the formation of a peptide chain from mRNA code that is being read by tRNA molecules associated to the next amino acid in the growing peptide.
