The DNA of most bacteria is contained in a single circular molecule, called the bacterial chromosome. The chromosome, along with several proteins and RNA molecules, forms an irregularly shaped structure called the nucleoid. This sits in the cytoplasm of the bacterial cell.
Urine tests for diabetes facts. 1  Urine tests may be done in people with diabetes to evaluate severe hyperglycemia (severe high blood sugar) by looking for ketones in the urine.  Ketones are a metabolic product produced when fat is metabolized. Ketones increase when there is insufficient insulin to use glucose for energy.
Test for glycosuria, the excretion of glucose in the urine. The test for urine glucose uses a small dipstick that changes color after it has been dipped in urine.Matching the color on the dipstick against a chart on the test package reveals whether there is glucose in the urine.irst, the renal threshold â the blood glucose level at which the kidneys begin to excrete glucose in the urine â is relatively high. In healthy, nondiabetic individuals, the average renal threshold is at a blood glucose level of 160â180 mg/dl.
