  2. Cloning vector - Wikipedia

    en.wikipedia.org/wiki/Cloning_vector

    Cosmids are plasmids that incorporate a segment of bacteriophage λ DNA that has the cohesive end site (cos) which contains elements required for packaging DNA into λ particles. Under apt origin of replication (ori), it can replicate as a plasmid.

  3. Mobile genetic elements - Wikipedia

    en.wikipedia.org/wiki/Mobile_genetic_elements

    Before site specific recombination can occur, the oligonucleotide ends must be filled. The ligation of these ends generates a replication fork at each end of the transposable element. The single strand displacement causes synthesis from the un-ligated 3' hydroxyl group to form long single stranded sections adjacent to the 5' end.

  4. BamHI - Wikipedia

    en.wikipedia.org/wiki/BamHI

    BamHI, like other type II restriction endonucleases, often requires divalent metals as cofactors to catalyze DNA cleavage. [2] Two-metal ion mechanism is one of the possible catalytic mechanisms of BamHI since the BamHI crystal structure has the ability to bind two metal ions at the active site, which is suitable for the classical two-metal ion mechanism to proceed.

  5. Lambda phage - Wikipedia

    en.wikipedia.org/wiki/Lambda_phage

    The integration of phage λ takes place at a special attachment site in the bacterial and phage genomes, called att λ. The sequence of the bacterial att site is called attB, between the gal and bio operons, and consists of the parts B-O-B', whereas the complementary sequence in the circular phage genome is called attP and consists of the parts ...

    en.wikipedia.org/wiki/P1-derived_artificial...

    A P1-derived artificial chromosome, or PAC, is a DNA construct derived from the DNA of P1 bacteriophages and Bacterial artificial chromosome.It can carry large amounts (about 100–300 kilobases) of other sequences for a variety of bioengineering purposes in bacteria.

  7. Bacteriophage - Wikipedia

    en.wikipedia.org/wiki/Bacteriophage

    A bacteriophage (/ b æ k ˈ t ɪər i oʊ f eɪ dʒ /), also known informally as a phage (/ ˈ f eɪ dʒ /), is a virus that infects and replicates within bacteria and archaea. The term is derived from Ancient Greek φαγεῖν (phagein) 'to devour' and bacteria .

    A science project is an educational activity for students involving experiments or construction of models in one of the science disciplines. Students may present their science project at a science fair, so they may also call it a science fair project. Science projects may be classified into four main types.
