Regulation and Tracking in Nonlinear Systemsr question is why certain genes are expressed only in particular plant tissues and at specific times during development. This knowledge is essential for creating improved varieties by genetic engineering. Some current research aimed at using gene transfer to study the developmental regulation of pla

Therefore, one should be able to transfer polygenic traits via chromosome-mediated transformation..One serious problem with chromosome-mediated transformation is the lack of suitable methods for the introduction of the foreign

Lectures in Magnetohydrodynamics. The physiological role of Zn has centered on its interaction with enzymes. For example, the cessation of growth associated with nutritional Zn deficiency involves a reduction in DNA polymerase activity and concomitant reduction in DNA synthesis. Similarly, RNA polymerases I, II, and III are all Zn
