George Smith and Greg Winter developed a technology that uses these biological agents for the directed evolution of novel antibodies. (15[1])The genome of one of these species, named MS2, was the first to be completely sequenced and contains just 4 genes. Seymour Benzer discovered the cistron through his work on the rapid lysis II mutant of one of these species. A ‘moron’ is a gene with no advantage to one of these organisms produced during its (*) lysogenic life cycle. (10[1])These biological agents (10[1])provided selective pressure in the Luria-Delbrück experiment, which demonstrated that genetic mutations in bacteria are random. That experiment used the T1 type of these agents which also have a ‘lambda’ type. These viruses have been proposed as a treatment for multidrug-resistant bacteria. For 10 points, what viruses are named for their ability to infect and ‘eat’ bacteria? ■END■
