Document Summary
In eukaryotes, mrna is processed in the nucleus then exported to the cytoplasm where it is translated. In prokaryotes, transcription and translation are coupled (there is no nucleus in bacteria) Prokaryotes translation beings before transcription is complete. Mrna can associate with ribosomes as they are being formed. Can make different proteins with the same. Polycistronic rna can encode proteins with similar functions. Can encode only one protein and only has one start and stop codon. Transfer rna brings amino acid and has the anticodon on the bottom that matches with the mrna.
