What is bacteriophage lambda?
What is bacteriophage lambda?
Phage lambda (λ) is a temperate phage, and therefore on infection of a bacterial cell, one of two alternative pathways may result; Bacteriophage lambda can reproduce in two alternative modes of growth.
What is the genome size of the lambda phage?
Lambda contains a linear double stranded DNA genome of 48.5 KB. Lambda phage exists in two form. Inside the phage it is linear double stranded DNA; inside host double stranded circular DNA molecule. 1.
How does the lambda phage bind to the E coli cell?
Bacteriophage Lambda binds to an E. coli cell by means of its J protein in the tail tip. The J protein interacts with the maltose outer membrane porin (the product of the lamB gene) of E. coli, a porin molecule, which is part of the maltose operon. The linear phage genome is injected through the outer membrane.
What is the life cycle of lambda phage and T4?
The life-cycle of lambda phage begins when it absorbs to the surface of the host bacterial cell. The J maltodextrin). As for T4, initial adhesion is reversible but it triggers a change in the phage that results
