Genetic map of lambda phage
WebA bacteriophage, or phage for short, is a virus that infects bacteria. Like other types of viruses, bacteriophages vary a lot in their shape and genetic material. Phage genomes … Web17. Transcriptional regulation in bacteriophage lambda B. Map of λ Figure 4.3.4. 1. DNA from a λ phage particle is linear, but the ends are complementary cohesive ends (cos). Thus when the phage DNA is injected into a cell upon infection, the ends anneal to form a circle. Maps of λ DNA are frequently drawn from the left cos site to the right
