Lambda phage is a non-contractile tailed phage, meaning during an infection event it cannot 'force' its DNA through a bacterial cell membrane. It must instead use an existing pathway to invade the host cell, having evolved the tip of its tail to interact with a specific pore to allow entry of its DNA to the hosts.
A cosmid is a type of hybrid plasmid that contains a Lambda phage cos sequence. [1] Often used as cloning vectors in genetic engineering, cosmids can be used to build genomic libraries. They were first described by Collins and Hohn in 1978. [2] Cosmids can contain 37 to 52 (normally 45) kb of DNA, limits based on the normal bacteriophage ...
When the Integration Host Factor was first discovered, it was only known for the site-specific recombination of bacteriophage. [4] This is all we knew for a while but through another article, we were able to find that with further research, IHF plays a key role in the scope of physiological processes of E. Coli, including site-specific recombination activities, phage packaging and partitioning ...

Lambdavirus (synonyms Lambda-like viruses, Lambda-like phages, Lambda phage group, Lambda phage) is a genus of viruses in the order Caudovirales, in the family Siphoviridae. Bacteria serve as natural hosts, with transmission achieved through passive diffusion. There are five species in this genus.

Temperate phages (such as lambda phage) can reproduce using both the lytic and the lysogenic cycle. [4] How a phage decides which cycle to enter depends on a variety of factors. [5] For instance, if there are several other infecting phages (or if there is a high multiplicity), it is likely that the phage will use the lysogenic cycle.
