A microarray differs from a gene fusion in that, it

is not constructed by cloning

gives direct measurement of mRNA level

All of these

carries DNA segments from many different genes

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

have the promoter of lacZ or some other reporter gene
