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

allow to monitor the expression of all genes with a promoter similar in sequence to Px
have Px but not the rest of the X coding region
give the same information as from a microarray
have the promoter of lacZ or some other reporter gene

a small deletion occurs in the transposase gene of an IS element
a small deletion occurs in the transposase gene of an IS element and plasmid is integrated
an IS element integrates with another IS element with the help of a plasmid
two IS elements integrate into a chromosome with only a small distance separating them
