How can transgenic organisms be used to identify transcriptional enhancers?
A) A reporter gene can be constructed so that its expression is controlled by an enhancer that may potentially exist within a fragment of genomic DNA. B) A reporter gene can be expressed in every tissue. C) A gene that is normally expressed in the organism can be cloned under the control of different regulatory elements so that it is expressed in all tissues. D) A transgene can be integrated in a site that disrupts a gene to determine whether that gene is essential for the cell or organism.
