Answer: The bacteria that glows in the presence of lactose will fluorescence under ultraviolet light.

Explanation:

Bacteria growing in the presence of lactose will fluoresce under ultraviolet light as well. The gene that is responsible for the fluorescence will be inserted in E.coli and the gene that is replaced is lac Z gene.

The lac Z gene when replaced by the green fluorescent protein then the bacteria will glow in the presence of ultraviolet light.
