The genetic material for nearly all life on Earth. recombinationplugin-autotooltip__default plugin-autotooltip_bigRecombination: Recombination can have slightly different meanings depending on context:
* In the context of genetic crosses (usually a dihybrid cross or a test cross), recombination refers to the phenomena where the phenotype of the F2 offspring is different than either parent (P generation). $lox$ system derived from bacteriophageplugin-autotooltip__default plugin-autotooltip_bigBacteriophage: viruses that infect bacteria.

In DNA, it refers to the order of G, A, T, and C nucleotides. In RNA, it refers to the order of G, A, U, and C nucleotides. In proteins, it refers to the order of amino acids.. Very commonly used in various reverse geneticplugin-autotooltip__default plugin-autotooltip_bigReverse genetics: an approach to studying genes wherein a researcher starts with knowledge of the physical identity of a gene (i.e., the DNA sequence of the gene) but does not know its function. In reverse genetics, the researcher uses various molecular genetic tools to create modified alleles that are reintroduced into an organism, with the goal of trying to deduce the function of the experiments.
