Chapt er 12, page 15 Chapt er 12 Highlights: I. One Gene, One Polypeptide II. DNA, RNA, and the Flow of Information A. RNA differs from DNA B. Information flows in one direction when genes are expressed C. RNA viruses modify the central dogma III. Transcription: DNA-Directed RNA Synthesis A. Initiation of transcription requires a promoter and RNA polymerase B. RNA polymerase elongates the transcript C. Transcription terminates at particular base sequences IV. The Genetic Code A. The genetic code is redundant but not ambiguous B. The genetic code is (nearly) universal C. Biologists deciphered the genetic code by using artificial messengers V. Preparation for Translation: Linking RNAs, Amino Acids, and Ribosomes A. Activating enzymes link the right tRNAs and amino acids B. The ribosome is the workbench for translation VI. Translation: RNA-Directed Polypeptide Synthesis A. Translation begins with an initiation complex B. The polypeptide elongates from the N terminus C. Elongation continues and the polypeptide grows
