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

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
have the promoter of lacZ or some other reporter gene
give the same information as from a microarray
