Consider a 1000-l CSTR in which biomass is being produced with glucose as the substrate. The microbial system follows a Monod relationship withn µ_m = 0.4 h^-1 , K_S = 1.5 g/l (an unusu ally high value), and the yield factor Y_X/S = 0.5 g biomass/g substrate consumed. If normal operation is with a sterile feed containing 10 g/l glucose at a rate of 100 l/h. What is the specific biomass production rate (g/l-h) at steady state?

Which group of VNTRs are tandem are frequently distributed in all eukaryotic genomes (except yeast) examined so far. They show a large, stable 'polymorphism due to variation in the number of repeat units and are almost 'ideal as molecular markers for genome mapping.

Cloning techniques can be used not only to overproduce proteins but to produce protein products altered, subtly or dramatically, from their native forms. Specific amino acids may be replaced individually by
