Textbook Question
Chapter 16, Problem 34P
In 2005, Frederick Blattner and his colleagues found that E. coli cells have a global transcriptional program that helps them forage for better sources of carbon. Many genes, including genes needed for bacterial motility, are turned on in response to poorer carbon sources so that the bacteria can search for better nutrition. You now want to search for genes that regulate this response. How could you use lacZ fusions to try to identify such regulatory genes?

You intend to insert patched dominant negative DNA into the left half of the neural tube of a chick.
1) Which side of the neural tube would you put the positive electrode to ensure that the DNA ends up on the left side?
2) What would be the internal (within the embryo) control for this experiment?
3) How can you be sure that the electroporation method itself is not impacting the embryo?
4) What would you do to ensure that the electroporation is working? How can you tell?
