Topic 1: THE CODE IS DEGENERATE Topic 2: THREE RULES GOVERN THE GENETIC CODE Topic 3: SUPPRESSOR MUTATIONS CAN RESIDE IN THE SAME OR A DIFFERENT GENE Topic 4: THE CODE IS NEARLY UNIVERSAL
Q1. Prokaryotic cell E. coli consists of a single closed-circular DNA molecule of 4.6 x 106 bp long. This DNA molecule would be 1.6 mm if the double helix is relaxed. Please describe what strategies does E. coli use to pack such a long molecules into its nucleoid less than a micrometer (mm) in diameter. (20 points)
