  2. Lambda phage - Wikipedia

    en.wikipedia.org/wiki/Lambda_phage

    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.

  3. Cosmid - Wikipedia

    en.wikipedia.org/wiki/Cosmid

    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 ...

  4. Site-specific recombination - Wikipedia

    en.wikipedia.org/wiki/Site-specific_recombination

    The earliest identified members of the serine recombinase family were known as resolvases or DNA invertases, while the founding member of the tyrosine recombinases, lambda phage integrase (using attP/B recognition sites), differs from the now well-known enzymes such as Cre (from the P1 phage) and FLP (from the yeast Saccharomyces cerevisiae).

  5. CII protein - Wikipedia

    en.wikipedia.org/wiki/CII_protein

    cII is the central “switchman” in the lambda phage bistable genetic switch, allowing environmental and cellular conditions to factor into the decision to lysogenize or to lyse its host. [ 4 ] cII acts as a transcriptional activator of three promoters on the phage genome : pI, pRE, and pAQ.

  6. Integration host factor - Wikipedia

    en.wikipedia.org/wiki/Integration_host_factor

    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 ...

  7. Lysogenic cycle - Wikipedia

    en.wikipedia.org/wiki/Lysogenic_cycle

    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.

    Typically, dementia is associated with classic symptoms like confusion and memory loss. But new research finds that there could be a less obvious risk factor out there: your cholesterol levels ...

  9. Cre-Lox recombination - Wikipedia

    en.wikipedia.org/wiki/Cre-Lox_recombination

    Phages like the lambda phage use their site specific recombinases to integrate their DNA into the host genome during lysogeny. P1 phage DNA on the other hand, exists as a plasmid in the host. The Cre-lox system serves several functions in the phage: it circularizes the phage DNA into a plasmid, separates interlinked plasmid rings so they are ...
