Replication, Transcription, Translation ◼ Repetitive processes Build polymers of nucleotides or amino acids ◼ Each has 3 major steps Initiation • Bind polymerizing machine, first monomer to template • DNA polymerase, RNA polymerase, Ribosome ◼ Elongation Read template, add next monomer • DNA, RNA, Protein ◼ Termination Release machine and completed product
