The virus particle consists of a head and a tail that can have tail fibers. The whole particle consists of 12–14 … See more

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 evol… See more

Multiplicity reactivation (MR) is the process by which multiple viral genomes, each containing inactivating genome damage, interact within an infected cell to form a viable viral genome. MR was originally discovered … See more

The repressor found in the phage lambda is a notable example of the level of control possible over gene expression by a very simple system. It forms a 'binary switch' with two genes under mutually exclusive expression… See more

An important distinction here is that between the two decisions; lysogeny and lysis on infection, and continuing lysogeny or lysis from a prophage. The latter is determined solely by the activation of RecA in the SOS … See more

Lambda phage has been used heavily as a model organism and has been an excellent tool first in microbial genetics, and then later in molecular genetics. Some of its uses include its application as a vector for the cloning of … See more
