The expression of gene X (which has promoter Px) is to be monitored. A gene fusion construction for carrying this work will

have the promoter of lacZ or some other reporter gene

have Px but not the rest of the X coding region

allow to monitor the expression of all genes with a promoter similar in sequence to Px

give the same information as from a microarray
