Please acknowledge the Principal … WebApr 17, 2014 · In this way, arabinose is absolutely needed for induction. Another widely used approach is to place a gene under the control of a regulated phage promoter. The strong leftward promoter (pL) of phage lambda directs expression of early lytic genes (Dodd et al., 2005). The promoter is tightly repressed by the λcI repressor protein, which sits on ...
