Chapter 5 Topics 5.1 Displacing nucleosomes.
Transcription can occur even in a region of nucleosomes.
If the promoter is accessible to RNA polymerase and transcription factors, the presence of nucleosomes will not inhibit the elongation of the message. 5.2 Structure of the 5' cap. If the cap is missing or unmethylated, translation may fail to occur. 5.3 Promoter struct ure and the mechanisms of transcription complex assembly. Getting RNA polymerase to a promoter is not an easy task.
