Obtain your Petri dish and observe the bacterial growth on the plate. 2. If you have clear areas where bacteria did not grow around your antibiotic discs‚ these are called ’zones of inhibition.’ Turn the plate so that you can place a ruler against the back of the Petri dish and measure the diameter of the zone of inhibition in millimeters. Record your own data in Table 1 below. 3

Genetics: the science of heredity that includes the study of what genes are‚ how they carry info‚ how they are replicated and passed to subsequent generations of cells or passed between organisms‚ and how the expression of their info within an organism determines the particular characteristics of that organism. Genome: the cell’s genetic information that includes it’s plasmids and chromosome. Chromosomes: structures containing DNA that physically carry hereditary info‚ contain the genes Genes:
