The International Grape Genomics Program (IGGP) is a collaborative genome project dedicated to determining the genome sequence of the grapevine Vitis vinifera. It is a multinational project involving research centers in Australia , Canada , Chile , France , Germany , Italy , South Africa , Spain , and the United States .
The first cosmic ray experiment was started in 1955 by B. V. Sreekantan by setting up cloud chambers that heralded the beginning of research at the Cosmic Ray Laboratory (CRL) in Ooty. [ citation needed ] The next decade witnessed a variety of experiments involving high energy interactions and extensive air shower studies in this laboratory.
In genetics, a strain is said to be auxotrophic if it carries a mutation that renders it unable to synthesize an essential compound. For example, a yeast mutant with an inactivated uracil synthesis pathway gene is a uracil auxotroph (e.g., if the yeast Orotidine 5'-phosphate decarboxylase gene is inactivated, the resultant strain is a uracil ...
Types of mutations that can be introduced by random, site-directed, combinatorial, or insertional mutagenesis. In molecular biology, mutagenesis is an important laboratory technique whereby DNA mutations are deliberately engineered to produce libraries of mutant genes, proteins, strains of bacteria, or other genetically modified organisms.
Breeding experiments to study evolution and genetics. Laboratory mice, flies, fish, and worms are inbred through many generations to create strains with defined characteristics. [200] These provide animals of a known genetic background, an important tool for genetic analyses.

This test often involves crossing two pure-breeding strains, such as white-eyed flies, from separate origins. The process entails mating two flies, each from a different strain. The eye color of the resulting progeny determines the outcome of the test. If the progeny exhibit red eyes, it indicates that the two strains complement each other.
Mention of Beadle and Tatum's 1958 Nobel prize on the monument at the American Museum of Natural History in New York City.. Although some instances of errors in metabolism following Mendelian inheritance patterns were known earlier, beginning with the 1902 identification by Archibald Garrod of alkaptonuria as a Mendelian recessive trait, for the most part genetics could not be applied to ...
