The expression of gene X (which has promoter Px) is to be monitored. A gene fusion construction for carrying this work will give the same information as from a microarray 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 have the promoter of lacZ or some other reporter gene TRUE ANSWER : ? YOUR ANSWER : ?
When composite transposons are formed an IS element integrates with another IS element with the help of a plasmid a small deletion occurs in the transposase gene of an IS element and plasmid is integrated two IS elements integrate into a chromosome with only a small distance separating them a small deletion occurs in the transposase gene of an IS element TRUE ANSWER : ? YOUR ANSWER : ?
