    In 2020, it was announced that Google's AlphaFold, a neural network based on DeepMind artificial intelligence, is capable of predicting a protein's final shape based solely on its amino-acid chain with an accuracy of around 90% on a test sample of proteins used by the team.

  3. McDonald–Kreitman test - Wikipedia

    en.wikipedia.org/wiki/McDonald–Kreitman_test

    The McDonald–Kreitman test [1] is a statistical test often used by evolutionary and population biologists to detect and measure the amount of adaptive evolution within a species by determining whether adaptive evolution has occurred, and the proportion of substitutions that resulted from positive selection (also known as directional selection).

  4. Biological tests of necessity and sufficiency - Wikipedia

    en.wikipedia.org/wiki/Biological_tests_of...

    Tests of sufficiency include a gain of function by discrete stimulation and isolation of a biological element to observe a change in the targeted event. These types of methods are imperative to several subfields of biology. Particularly, tests of sufficiency are common in the field of chronobiology.

  5. Phylogenetic comparative methods - Wikipedia

    en.wikipedia.org/wiki/Phylogenetic_comparative...

    Phylogenetic comparative methods (PCMs) use information on the historical relationships of lineages (phylogenies) to test evolutionary hypotheses.The comparative method has a long history in evolutionary biology; indeed, Charles Darwin used differences and similarities between species as a major source of evidence in The Origin of Species.

    [1] [6] Hence, there are multiple subdisciplines within biology, each defined by the nature of their research questions and the tools that they use. [7] [8] [9] Like other scientists, biologists use the scientific method to make observations, pose questions, generate hypotheses, perform experiments, and form conclusions about the world around ...

  9. Test cross - Wikipedia

    en.wikipedia.org/wiki/Test_cross

    To perform a test cross with C. elegans, place worms with a known recessive genotype with worms of an unknown genotype on an agar plate. Allow the male and hermaphrodite worms time to mate and produce offspring. Using a microscope, the ratio of recessive versus dominant phenotype will elucidate the genotype of the dominant parent. [9]
