Be sure to precisely indicate what you are labeling. Vague arrows will be marked wrong. The b-globin cluster resides on chromosome 11 in humans. The original globin gene might have undergone a gene duplication, creating an exact copy. This process of gene duplication and divergence was repeated a number of times during evolution to lead to the current b -globin gene cluster.
Lambda phage is called a transducing phage.
3 points A transducing phage is one that can transfer some DNA of the host organism from one cell to another through a normal infection process. The excised DNA, including the piece of host DNA, is then packaged into a phage and can deliver the new DNA into the next cell it infects. Your boss is upset and wants you to fix the problem by providing her with a bacterial culture that only contains the AmpR plasmids in the bacteria. You approach the problem by performing a transfection experiment using the mixed plasmid preparation. This creates a flask of bacteria containing one or both of these plasmids in each bacterial cell.
