It ended up growing because the LB that was in the plate with it helped the bacteria grow and reproduce. The bacteria became resistant to the ampicillin because the DNA plasmid contained beta lactamase which made the cell resistant to ampicillin. It did not end up glowing under UV light because the gene for the green fluorescent protein was repressed by the araC gene found on the DNA plasmid. The hypothesis about the +pGLO plate containing LB, ampicillin, and arabinose was correct because the bacteria did end up growing and glowing under UV light.…
