Final answer:
The transgene inserted into the E. coli and C. elegant for study is the Green Fluorescent Protein (GFP) gene, which is used for monitoring gene expression in organisms.
Step-by-step explanation:
The transgene that has been inserted into the E. coli and C. elegant for your lab study is likely to be the Green Fluorescent Protein (GFP) gene. This is a commonly used reporter gene which, under ultraviolet light, makes the organism fluoresce, indicating successful gene expression. While recombinant DNA technology has been used to produce other therapeutic proteins such as human insulin and human growth hormone (HGH) using E. coli, the GFP gene represents a powerful tool for monitoring gene expression patterns in real time within living organisms.
