Question 9

Under specific physiological conditions, a synthetic DNA plasmid contains a gene of length 13.530 kilobases13.530\text{ kilobases}13.530 kilobases that adopts the left-handed Z-DNA conformation. In this conformation, the double helix makes one complete turn every 12 base pairs12\text{ base pairs}12 base pairs. Each complete turn has a length of 4.56 nm4.56\text{ nm}4.56 nm.

Use this information to calculate the physical length in micrometres (μm\mu\text{m}μm) of this gene in its Z-DNA state. Give your answer to 3 significant figures.
