1. From chapter 6, figure. What has happened to the bacterial DNA in this illustration? What effect can this have on a bacterium? Is this temporary or permanent?

2. From chapter 9, process figure. Study the series of events in this illustration. What do cell A (step 1) and cell B (step 5) have incommon?

Donor (hoel chromosome Phage DNA Cell A A phage infecis cel A (the donor cell) by normal means Separated piece af host DNA Parts of phage During replicalion and assembly a phage particle incorporatesa segmenl of bacterial DNA by mistake. Cel A then lyses and releases he malure phages, including the genetically altered ane. Cell B The altered phage absorbs to and penelrates another host cell (cel B), injecting the DNA from cell A raiher than viral nucleic acid Lysis DNA from donor Cell B receives this donated ncorporaled into chromosome DNIA, which recombines wilh ils own DNA. Because the vinus is defeclive (biologically inactive as a virus), it is unable to complele a lytic cycle. The transduced oell survives and can use this new genetic malerial.
