Using Reporter Genes: Transgenic Technology: Part 2

Construct DNA containing the reporter gene is injected into an egg or an embryo and allowed to become integrated into the organism.

Because the reporter gene shares an identical regulatory region with the gene in question, it is expressed whenever and wherever the original gene is expressed in the organism.

An arrow labeled injected, points from the construct DNA containing the reporter gene to a sphere labeled egg which has an arrow pointing to a larger green circle labeled organism with a reporter gene.
Construct DNA containing the reporter gene injected into egg results in organism with reporter gene
