  2. Molecular cloning - Wikipedia

    en.wikipedia.org/wiki/Molecular_cloning

    Molecular cloning takes advantage of the fact that the chemical structure of DNA is fundamentally the same in all living organisms. Therefore, if any segment of DNA from any organism is inserted into a DNA segment containing the molecular sequences required for DNA replication, and the resulting recombinant DNA is introduced into the organism from which the replication sequences were obtained ...

  3. In vitro recombination - Wikipedia

    en.wikipedia.org/wiki/In_vitro_recombination

    Recombinant DNA (rDNA), or molecular cloning, is the process by which a single gene, or segment of DNA, is isolated and amplified. Recombinant DNA is also known as in vitro recombination . A cloning vector is a DNA molecule that carries foreign DNA into a host cell , where it replicates, producing many copies of itself along with the foreign DNA.

  4. Cloning - Wikipedia

    en.wikipedia.org/wiki/Cloning

    Molecular cloning refers to the process of making multiple molecules. Cloning is commonly used to amplify DNA fragments containing whole genes, but it can also be used to amplify any DNA sequence such as promoters, non-coding sequences and randomly fragmented DNA.

  5. Recombinant DNA - Wikipedia

    en.wikipedia.org/wiki/Recombinant_DNA

    The choice of vector for molecular cloning depends on the choice of host organism, the size of the DNA to be cloned, and whether and how the foreign DNA is to be expressed. [7] The DNA segments can be combined by using a variety of methods, such as restriction enzyme/ligase cloning or Gibson assembly. [citation needed]

  6. Genetic engineering techniques - Wikipedia

    en.wikipedia.org/wiki/Genetic_engineering_techniques

    The first step is to identify the target gene or genes to insert into the host organism. This is driven by the goal for the resultant organism. In some cases only one or two genes are affected. For more complex objectives entire biosynthetic pathways involving multiple genes may be involved.

  7. Gateway Technology - Wikipedia

    en.wikipedia.org/wiki/Gateway_Technology

    The first step in Gateway cloning is the preparation of a Gateway Entry clone. There are a few different ways to make entry clone. Gateway attB1 and attB2 sequences are added to the 5' and 3' end of a gene fragment, respectively, using gene-specific PCR primers and PCR amplification. The PCR amplification products are then mixed with a propriet

  8. DNA sequencing - Wikipedia

    en.wikipedia.org/wiki/DNA_sequencing

    Most sequencing approaches use an in vitro cloning step to amplify individual DNA molecules, because their molecular detection methods are not sensitive enough for single molecule sequencing. Emulsion PCR [ 69 ] isolates individual DNA molecules along with primer-coated beads in aqueous droplets within an oil phase.

  9. Plasmid preparation - Wikipedia

    en.wikipedia.org/wiki/Plasmid_preparation

    These methods invariably involve three steps: growth of the bacterial culture, harvesting and lysis of the bacteria, and purification of the plasmid DNA. [4] Purification of plasmids is central to molecular cloning. A purified plasmid can be used for many standard applications, such as sequencing and transfections into cells.
