Advantages
The primary advantage of this technique is its ability to eliminate any foreign DNA from the genome after the mutagenesis process. This ensures there are no selectable markers or exogenous sequences used for targeting left in the genome that may cause unforeseen effects.
The delitto perfetto technique is also simpler compared to other methods for in vivo site-directed mutagenesis. Other methods require multiple cloning steps and extensive DNA sequencing to confirm mutagenesis, which is often a complicated and inefficient process.
There is great flexibility in this approach because after the CORE cassette is inserted (see Method Overview for details), multiple mutations in the gene of interest can be made easily and quickly.
This method can be applied to other organisms where homologous recombination is efficient, such as the moss Physcomitrella patens, DT40 chicken cells, or E. coli. In addition, human genes can be studied and similarly genetically manipulated in yeast by using yeast artificial chromosomes (YACs).

Famous quotes containing the word advantages:
“Can you conceive what it is to native-born American women citizens, accustomed to the advantages of our schools, our churches and the mingling of our social life, to ask over and over again for so simple a thing as that “we, the people,” should mean women as well as men; that our Constitution should mean exactly what it says?”
—Mary F. Eastman, U.S. suffragist. As quoted in History of Woman Suffrage, vol. 4 ch. 5, by Susan B. Anthony and Ida Husted Harper (1902)
“The advantages found in history seem to be of three kinds, as it amuses the fancy, as it improves the understanding, and as it strengthens virtue.”
—David Hume (1711–1776)
“There is no one thoroughly despicable. We cannot descend much lower than an idiot; and an idiot has some advantages over a wise man.”
—William Hazlitt (1778–1830)
