Established in October 1945 with the objective of eliminating hunger and improving nutrition and standards of living by increasing agricultural productivity, FAO coordinates the efforts of governments and technical agencies in programs for developing agriculture, forestry, fisheries, and land and ...
The process of determining the amino-acid sequence of a protein or its component polypeptides.
Industry:Biotechnology
The process of drying a tissue or an organ in a frozen state under vacuum. Tissues are freeze-dried to measure their dry weight or to preserve them for future analysis. Freeze-drying is the standard way of preserving micro-organisms for long periods of time. <i>cf</i> lyophilization.
Industry:Biotechnology
The process of elucidating the nucleotide sequence of a gene.
Industry:Biotechnology
The process of generation of nucleotide changes in cloned genes by any one of several procedures, including site-specific and random mutagenesis. Also called <i>in vitro</i> mutagenesis.
Industry:Biotechnology
The process of heating (de-naturing step) and slowly cooling (re-naturing step) double-stranded DNA to allow the formation of hybrid DNA or complementary strands of DNA or of DNA and RNA.
Industry:Biotechnology
The process of polypeptide synthesis in which the amino acid sequence is determined by mRNA, mediated by tRNA molecules, and carried out on ribosomes.
Industry:Biotechnology
The process of replacing a stable atom in a compound with a radioactive isotope of the same element to enable it to be detected by autoradiography or other techniques. Increasingly, radioactive labelling is being replaced by fluorescent labelling. The method is used to trace the path of the labelled compound through a biological or chemical system.

Industry:Biotechnology
The process of selecting cells within a group of genetically different cells. Select cells or cell lines are sub-cultured onto fresh medium for continued selection and often are exposed to an increased level of the selection agent. The final objective is to regenerate plants exhibiting the traits selected for at the cellular level.
Industry:Biotechnology
The process of selecting genes, cells, clones, etc., within populations or between populations or species. Genetic selection usually results in differential success rates of different genotypes, reflecting many variables, including selection pressure and genetic variability in populations.
