Tīmeklis2016. gada 1. janv. · Lambda Phage. (λ) A temperate bacteriophage, an obligate parasite. It belongs to the family of lambdoid phages, that includes phages ϕ21, ϕ80, ϕ81, etc. Lambdoid phages are characterized by cohesive ends, the ability to recombine, and inducibility by UV.

TīmeklisThermo Scientific Lambda is a temperate Escherichia coli bacteriophage. The virion DNA is linear and double-stranded (48502 bp) with 12 bp single-stranded complementary 5’-ends. After the phage particle injects its chromosome into the cell, the chromosome circularizes by end joining.

Sie entstehen bei einer Sonderform der Replikation, wie sie in z.B. beim Lambda-Phagen vorkommt ( Rolling-circle-Replikation ). Concatemere werden im weiteren Verlauf durch Ribozyme aufgelöst.
