Freelancing is a way of independent earning from many projects and assignments that are available on freelancing websites. Freelance means that the worker is not bound by the policies of any company rather they are bound by the project they have been provided with.
Phage. Definition. noun, plural: phages. (1) A bacteriophage: a virus capable of infecting a bacterial cell, and may cause lysis to its host cell. (2) A suffix that means a thing that eats or devours (as macrophage). Supplement. Bacteriophages or phages have a specific affinity for bacteria.
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. Soon, the phage switches to a rolling circle replication similar to that used by phage M13. 2  The DNA is nicked and the 3â end serves as a primer. 3  Note that this does not release single copies of the phage genome but rather one long molecule with many copies of the genome: a concatemer.
