Chapter 11, Problem 10RQ
Summary Introduction
Various types of vectors are used for cloning purposes such as plasmids, viruses, artificial chromosomes, and cosmids. The use of these cloning vectors is used mainly depending on the length of the DNA sequence to be cloned and the host. The vector containing gene of interest is inserted into the selected host for replication.

The transfection reagent used to introduce plasmids to the HEK293 cells was a lipid
reagent. Why is lipid utilized for this procedure?
What is the role of X-gal? What color will cells with the plasmid be in the absence of X-gal? Why?
A shuttle vector is a vector (usually a plasmid) constructed so that it can propagate in two
different host species. One of the most common types of shuttle vectors is the
yeast shuttle
vector. Examples of such vectors derived from yeast are Yeast Episomal Plasmid (YEP),
Yeast Integrating Plasmid (YIP) and Yeast Replicating Plasmid (YRP). Why is YEP preferred
over YIP and YRP? Give your thoughts on this.

Scientists studying bacterial plasmids devised an experiment using recombinant DNA techniques to remove a section of DNA (gene atg-12) of a bacterial plasmid (pOKE103) and create a new plasmid (pOKE104) that did not contain the gene atg-12. The new plasmid was then incorporated within the DNA of the fungus Neurospora crassa in cellular studies. Which statement explains the expected heredity of fungi that incorporate pOKE104? A - Fungi that incorporate pOKE104 will produce the protein from gene atg-12 and have increased rates of malignant tumors. B - Fungi that incorporate pOKE104 will not produce the protein from gene atg-12 but will have a normal appearance.

This protein can break down the synthetic chemical X-gal, producing a blue product that stains the entire cell blue (but is harmless to the bacteria). At the beginning of the B-gal gene there are several unique restriction sites (some of them are shown in the diagram below). You wish to clone a 1.0-kb Xbal fragment into the pUC18 plasmid, so you cut the plasmid with Xbal and, after removing the enzyme, mix the Xbal-cut plasmid with the 1.0-kb fragment, ligate, and transform competent bacteria.
