Industry:Biotechnology
A duplex DNA molecule with one or more internal single-stranded regions.
Industry:Biotechnology
A fairly recent development in plant culture, consisting of highly branched roots of a plant. A plant tissue is treated with a culture of the bacterium <i>Agrobacterium rhizogenes</i>, which transfers part of its own plasmid DNA to the cells of an infected plant. This alters the plant's metabolism, including alterations in hormone levels, which in turn cause the explant to grow highly branched roots from the sites of infection. The roots branch much more frequently than the usual root system of that plant, and are also covered with a mass of tiny root hairs. Their most significant feature is that they produce secondary metabolites at levels similar to those made in the original plant. Thus they can be used as replacement plants for making such compounds as food flavours or fragrances.
Industry:Biotechnology
A family of 300-bp sequences occurring nearly a million times in the human genome.
Industry:Biotechnology
