Fig. 14.4. A schematic view of a eukaryotic gene, and steps required to produce a protein product. The gene consists of promoter and transcribed regions. The transcribed region contains introns, which do not contain coding sequence for proteins, and exons, which do carry the coding sequences for proteins. The first RNA form produced is heterogenous nuclear RNA (hn RNA), which contains both intronic and exonic sequences. The hnRNA is modified such that a cap is added at the 5 end (cap site), and a poly-A tail added to the 3 end. The introns are removed (a process called splicing) to produce the mature mRNA, which leaves the nucleus to direct protein synthesis in the cytoplasm. Py is pyrimidine (C or T).

A potentiometric sensor was developed by Martinez-Manez and co-workers in thick film technology. Ru02 was used as sensitive material whereas this active electrode surface was covered with a semipermeable polymeric (poly-isophthalamide diphenylsulfone, PIDS) or ceramic-based (Ti02) membrane. The measurement of DO could only be carried out effectively if other redox processes were excluded except the desired reaction which was produced by oxygen. This was achieved by covering the active electrode with a semipermeable polymeric or ceramic membrane which allowed to pass DO and excluded any other redox-active species present in solution. A schematic view of the DO potentiometric sensor is displayed in Fig. 3.2. 

In the case of Walde et al. (1994a) the synthesis of poly(A) - which can be viewed as a simple form of RNA - proceeded simultaneously with the self-reproduction of vesicles, thus providing a core and shell reproduction, as schematically illustrated in Figure 10.3. 

Figure 9.1 Schematic diagram of the Ocusert reservoir delivery system. The figure shows an exploded view of the different elements of the Ocusert system. Two rate-controlled membranes composed of poly[ethylene-co-(vinyl acetate)] enclose a drug reservoir. An opaque ring is added for ease of handling and visibility.
