In the nucleotides What is information used for? Tells how to make proteins How is this regulated? Genome Organization genome : the complete complement of an organisms genes, an organisms genetic material Bacterial genome organization- Single circular chromosome- Naked DNA- No introns - Located in the cytoplasm - Plasmids Do the differences in organization lead to functional differences?- Transcription and translation can occur simultaneously - Easy for the cells to take up foreign DNA (transformation) Gene Regulation Why Regulate? Energetics Control (Figure 18.2) Procaryotic Gene Regulation: OPERON STRUCTURE regulator gene, Promoter site, operator, structural genes Bacterial Operon- Promoter: tells RNA polymerase where to start; region that attracts the RNA polymerase; contains the tata box...
