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 ...
1. A sequence found in eukaryotes and certain eukaryotic viruses which can increase transcription of a gene when located (in either orientation) up to several kilobases from the gene concerned. These sequences usually act as enhancers when on the 5´ side (upstream) of the gene in question. However, some enhancers are active when placed on the 3´ side (downstream) of the gene. In some cases enhancer elements can activate transcription of a gene with no (known) promoter.
2. A substance or object that increases a chemical activity or a physiological process.
3. A major or modifier gene that increases a physiological process.
Industry:Biotechnology
1. A site on the surface of a catalyst at which activity occurs.
2. The site on the surface of an enzyme molecule that binds the substrate molecule.
Industry:Biotechnology
1. A small opening in the surface of a plant ovule through which the pollen tube passes prior to fertilization.
2. A small pore in some animal cells or tissues.
Industry:Biotechnology
1. A specialized network of vessels for the circulation of fluids throughout the body tissue of an animal.
2. The system of vascular tissue in plants.
Industry:Biotechnology
1. A state of apparent inactivity preceding a response; called also a latent phase.
2. The initial growth phase, during which cell number remains relatively constant, prior to rapid growth.
3. The first of five growth phases of most batch-propagated cell suspension cultures, being the phase in which inoculated cells in fresh medium adapt to the new environment and prepare to divide.
Industry:Biotechnology
1. A substance or object that increases a chemical activity or a physiological process.
2. A DNA sequence that increases the transcription of a eukaryotic gene when they are both on the same DNA molecule. a.k.a. enhancer element; enhancer sequence.
Industry:Biotechnology
1. A substance or physical agent that stimulates transcription of a specific gene or operon.
2. A compound that, by binding to an allosteric site on an enzyme, enables the active site of the enzyme to bind to the substrate.
Industry:Biotechnology
1. A synthetic double-stranded oligonucleotide that has a blunt end, while the other end has a nucleotide extension that can base pair with a cohesive end created by cleavage of a DNA molecule with a specific type II restriction endonuclease. The blunt end of the adaptor can be ligated to the ends of a target DNA molecule and the construct can be cloned into a vector by using the cohesive ends of the adaptor.
2. A synthetic single-stranded oligonucleotide that, after self-hybridization, produces a molecule with cohesive ends and an internal restriction endonuclease site. When the adaptor is inserted into a cloning vector by means of the cohesive ends, the internal sequence provides a new restriction endonuclease site.
Industry:Biotechnology
1. An aggregate of identical cells (clones) derived from a single progenitor cell.
2. A group of interdependent cells or organisms.
Industry:Biotechnology
1. An aseptic viable explant.
2. A suspension culture subjected to several passages with a constant cell number per unit time.
