First explain how zygotic induction of lambda phage lysis occurs during bacterial conjugation (use a drawing if you want too, take picture to upload). Second, compare this form of induction to ultraviolet radiation (UV) exposure. Make sure you recall the molecules or pathways involved. Key terms: repressor (R), immunity, Iysogeny, conjugation, lytic, RecA. Finally, explain how zygotic induction provides key experimental evidence about how lambda provides immunity and lysogenic fate upon infection..
