The region of DNA that is upstream from a gene or genes and to which one or more regulatory proteins (repressor or activator) binds to control the expression of the gene(s).
Industry:Biotechnology
The relationship between the two strands of a double helix of DNA. Thymine in one strand pairs with adenine in the other strand, and cytosine in one strand pairs with guanine in the other strand.
Industry:Biotechnology
The relative proportion of auxin to cytokinin present in plant-tissue-culture media. Varying the relative amounts of these two hormone groups in tissue culture formulae affects the proportional growth of shoots and roots <i>in vitro</i>. As the ratio is increased (increased auxin or decreased cytokinin), roots are more likely to be produced, and as it is decreased root growth declines and shoot initiation and growth are promoted. This relationship was first recognized by C.O. Miller and F. Skoog in the 1950s.
Industry:Biotechnology
The removal of cells, tissues or organs of animals and plants for observation of their growth and development in appropriate culture media.
Industry:Biotechnology
The removal of halogen atoms (chlorine, iodine, bromine, fluorine) from molecules, usually during biodegradation.
Industry:Biotechnology
The repair or replacement of a defective gene within the gamete-forming tissues, resulting in a heritable change in an organism's genetic constitution.
Industry:Biotechnology
The result of combining DNA fragments from different sources.
Industry:Biotechnology
The result of nuclear divisions without subsequent cytoplasmic division (cytokinesis); the polyploids so obtained are called endopolyploids.
Industry:Biotechnology
The retention of juvenile body characters in the adult state, or the occurrence of adult characters in the juvenile state.
