Ends When
Replication DNA DNA DNA polymerase, primase, helicase, DNA ligase, topoisomerase Origin of replication (ORI)

Replication forks meet
Transcription RNA DNA RNA polymerase Promoter

Termination sequence
Translation Polypeptide (protein) mRNA Ribosome, tRNA Start codon (AUG)

Stop codon (UAA, UGA, UAG)
