  2. Sticky and blunt ends - Wikipedia

    en.wikipedia.org/wiki/Sticky_and_blunt_ends

    The simplest DNA end of a double stranded molecule is called a blunt end. Blunt ends are also known as non-cohesive ends. In a blunt-ended molecule, both strands terminate in a base pair. Blunt ends are not always desired in biotechnology since when using a DNA ligase to join two molecules into one, the yield is significantly lower with blunt ...

  3. Ligation (molecular biology) - Wikipedia

    en.wikipedia.org/wiki/Ligation_(molecular_biology)

    The mechanism of the ligation reaction was first elucidated in the laboratory of I. Robert Lehman. [4] [5] Two fragments of DNA may be joined by DNA ligase which catalyzes the formation of a phosphodiester bond between the 3'-hydroxyl group (-OH) at one end of a strand of DNA and the 5'-phosphate group (-PO4) of another.

  4. Lambda phage - Wikipedia

    en.wikipedia.org/wiki/Lambda_phage

    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, as discovered by Barbara J. Meyer .

  5. Cosmid - Wikipedia

    en.wikipedia.org/wiki/Cosmid

    Those cells which did not take up the cosmid would be unable to grow. [3] Unlike plasmids, they can also be packaged in vitro into phage capsids, a step which requires cohesive ends, also known as cos sites also used in cloning with a lambda phage as a vector, however nearly all the lambda genes have been deleted with the exception of the cos ...

  6. Lysogenic cycle - Wikipedia

    en.wikipedia.org/wiki/Lysogenic_cycle

    The prokaryotic cell is shown with its DNA, in green. 2. The bacteriophage attaches and releases its DNA, shown in red, into the prokaryotic cell. 3. The phage DNA then moves through the cell to the host's DNA. 4. The phage DNA integrates itself into the host cell's DNA, creating prophage. 5. The prophage then remains dormant until the host ...

  7. 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 ...

    A Florida man is accused of beating another man to death with golf clubs on a course in Palm Beach County. A probable cause affidavit filed by the Palm Beach Gardens Police Department obtained by ...

  9. Cell adhesion - Wikipedia

    en.wikipedia.org/wiki/Cell_adhesion

    Schematic of cell adhesion. Cell adhesion is the process by which cells interact and attach to neighbouring cells through specialised molecules of the cell surface. This process can occur either through direct contact between cell surfaces such as cell junctions or indirect interaction, where cells attach to surrounding extracellular matrix, a gel-like structure containing molecules released ...
