  3. Muller's ratchet - Wikipedia

    en.wikipedia.org/wiki/Muller's_ratchet

    Illustration of chromosome crossover during genetic recombination. In evolutionary genetics, Muller's ratchet (named after Hermann Joseph Muller, by analogy with a ratchet effect) is a process which, in the absence of recombination (especially in an asexual population), results in an accumulation of irreversible deleterious mutations.

  4. Mutation accumulation experiments - Wikipedia

    en.wikipedia.org/wiki/Mutation_accumulation...

    A mutation accumulation (MA) experiment is a genetic experiment in which isolated and inbred lines of organisms (so-called MA lines) are maintained such that the effect of natural selection is minimized, with the aim of quantitatively estimating the rates at which spontaneous mutations (mutations not caused by exogenous mutagens) occur in the studied organism.

    en.wikipedia.org/wiki/Luria–Delbrück_experiment

    In their experiment, Luria and Delbrück inoculated a small number of bacteria (Escherichia coli) into separate culture tubes. After a period of growth, they plated equal volumes of these separate cultures onto agar containing the T1 phage (virus). If resistance to the virus in bacteria were caused by an induced activation in bacteria i.e. if ...

    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 .

    en.wikipedia.org/wiki/Genetic_engineering_techniques

    Human-directed genetic manipulation began with the domestication of plants and animals through artificial selection in about 12,000 BC. [1]: 1 Various techniques were developed to aid in breeding and selection. Hybridization was one way rapid changes in an organism's genetic makeup could be introduced. Crop hybridization most likely first ...

    Hershey–Chase experiment proves that phage genetic material is DNA. 1952: The Hershey–Chase experiment proves the genetic information of phages (and, by implication, all other organisms) to be DNA. [29] 1952: an X-ray diffraction image of DNA was taken by Raymond Gosling in May 1952, a student supervised by Rosalind Franklin. [30]

    The Crick, Brenner et al. experiment (1961) was a scientific experiment performed by Francis Crick, Sydney Brenner, Leslie Barnett and R.J. Watts-Tobin. It was a key experiment in the development of what is now known as molecular biology and led to a publication entitled "The General Nature of the Genetic Code for Proteins" and according to the historian of Science Horace Judson is "regarded ...
