  2. Plasmid preparation - Wikipedia

    en.wikipedia.org/wiki/Plasmid_preparation

    Plasmid miniprep. 0.8% agarose gel ethidium bromide-stained.. A plasmid preparation is a method of DNA extraction and purification for plasmid DNA.It is an important step in many molecular biology experiments and is essential for the successful use of plasmids in research and biotechnology.

  3. Hershey–Chase experiment - Wikipedia

    en.wikipedia.org/wiki/Hershey–Chase_experiment

    Hershey and Chase, along with others who had done related experiments, confirmed that DNA was the biomolecule that carried genetic information. Before that, Oswald Avery, Colin MacLeod, and Maclyn McCarty had shown that DNA led to the transformation of one strain of Streptococcus pneumoniae to another. The results of these experiments provided ...

  4. Recombinant DNA - Wikipedia

    en.wikipedia.org/wiki/Recombinant_DNA

    The idea of recombinant DNA was first proposed by Peter Lobban, a graduate student of Prof. Dale Kaiser in the Biochemistry Department at Stanford University Medical School. [32] The first publications describing the successful production and intracellular replication of recombinant DNA appeared in 1972 and 1973, from Stanford and UCSF.

  5. DNA microarray - Wikipedia

    en.wikipedia.org/wiki/DNA_microarray

    This is an example of a DNA microarray experiment which includes details for a particular case to better explain DNA microarray experiments, while listing modifications for RNA or other alternative experiments. The two samples to be compared (pairwise comparison) are grown/acquired. In this example treated sample and untreated sample .

  6. 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 ...

  7. Genetic testing - Wikipedia

    en.wikipedia.org/wiki/Genetic_testing

    Genetic testing, also known as DNA testing, is used to identify changes in DNA sequence or chromosome structure. Genetic testing can also include measuring the results of genetic changes, such as RNA analysis as an output of gene expression , or through biochemical analysis to measure specific protein output.

  8. Meselson–Stahl experiment - Wikipedia

    en.wikipedia.org/wiki/Meselson–Stahl_experiment

    The Meselson–Stahl experiment is an experiment by Matthew Meselson and Franklin Stahl in 1958 which supported Watson and Crick's hypothesis that DNA replication was semiconservative. In semiconservative replication, when the double-stranded DNA helix is replicated, each of the two new double-stranded DNA helices consisted of one strand from ...

  9. Cold Spring Harbor Laboratory - Wikipedia

    en.wikipedia.org/wiki/Cold_Spring_Harbor_Laboratory

    The DNA Learning Center (DNALC), founded in 1988, was among the early pioneers [23] in developing hands-on genetics lab experiences for middle and high school students. In 2013, 31,000 students on Long Island and New York City were taught genetics labs at the DNALC and satellite facilities in New York.
