  2. R-loop - Wikipedia

    en.wikipedia.org/wiki/R-loop

    Schematic representation of factors promoting R-loop formation and stabilization. An R-loop is a three-stranded nucleic acid structure, composed of a DNA:RNA hybrid and the associated non-template single-stranded DNA. R-loops may be formed in a variety of circumstances and may be tolerated or cleared by cellular components.

  4. Genetic engineering techniques - Wikipedia

    en.wikipedia.org/wiki/Genetic_engineering_techniques

    If a vital gene is knocked out it can prove lethal to the organism. In order to study the function of these genes, site specific recombinases (SSR) were used. The two most common types are the Cre-LoxP and Flp-FRT systems. Cre recombinase is an enzyme that removes DNA by homologous recombination between binding sequences known as Lox-P sites ...

  5. Recombinant DNA - Wikipedia

    en.wikipedia.org/wiki/Recombinant_DNA

    Recombinant DNA molecules are sometimes called chimeric DNA because they can be made of material from two different species like the mythical chimera. rDNA technology uses palindromic sequences and leads to the production of sticky and blunt ends. The DNA sequences used in the construction of recombinant DNA molecules can originate from any ...

  6. Genetic recombination - Wikipedia

    en.wikipedia.org/wiki/Genetic_recombination

    Recombination can be artificially induced in laboratory (in vitro) settings, producing recombinant DNA for purposes including vaccine development. V(D)J recombination in organisms with an adaptive immune system is a type of site-specific genetic recombination that helps immune cells rapidly diversify to recognize and adapt to new pathogens .

  7. DNA sequencing - Wikipedia

    en.wikipedia.org/wiki/DNA_sequencing

    DNA sequencing is the process of determining the nucleic acid sequence – the order of nucleotides in DNA. It includes any method or technology that is used to determine the order of the four bases: adenine, guanine, cytosine, and thymine. The advent of rapid DNA sequencing methods has greatly accelerated biological and medical research and ...

    STRmix’s technology promises to help solve what has long been an issue in DNA analysis: The tinier the sample and the more complex it is — if it contained genetic material from multiple people ...

  9. 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 ...
