Examine each of the situations below and for each indicate the product of the OPP that is most important in that particular situation (a) cell division I nutrient reduction (c) synthesis of secondary cell wall (d) protein synthesis
- explain what scaffold hopping is and why it is useful for drug development?Experiment: In this activity yo Page 5 ze the results of experiments that investigate nutritional requirement of several mutant strains of yeast. The mutations in these strains cause a nutritional requirement for an amino acid, such that the strains will not grow in media that lack one specific amino acid. Any mutant that has a nutritional requirement is called an auxotroph, and is incapable of growing in a "minimal medium" containing only a carbon source (e.g., glucose), a simple nitrogen source (e.g., ammonium sulfate), and various salts and minerals. Such strains can be supported on a medium supplemented with only the missing nutrient or on a "rich" medium that contains amino acids, vitamins, nitrogenous bases, etc. (often in the form of an extract from yeast). The wild-type individual that can synthesize the metabolic component is a prototroph, and is capable of growth on minimal medium. The mutant strains in this activity are unable to synthesize tryptophan, lysine, or histidine;…25) In biomaterials design enginnering the surface properties effect the biological interactions (TRUE/FALSE) Chemotaxis Production of ECM Migration of the cells Composition of ECM Responsiveness to extracellular signaling 26) The principal functions of the ECM are ; EXCEPT a) Mechanical support for cell anchorage b) Cell proliferation c) Regulates and determine cells dynamic behaviour: d) Scaffolding for orderly tissue renewal
