Aspartase enzyme is used industrially for manufacture of aspartic acid, a component of low-calorie sweetener. Fumaric acid and ammonia are converted to aspartic acid according to the equation:

 

                                        

Under investigation is a process using aspartase in intact Bacillus cadaveris cells. In the substrate range of interest, the conversion can be described using Michaelis-Menten kinetics with K m 4.0 gl^-1. The substrate solution contains 15% (w/v) ammonium fumarate; enzyme is added in the form of lyophilised cells and the reaction stopped when 85% of the substrate is converted. At 32⁰C vmax for the enzyme is 5.9 g l^-1h^-1 and its half-life is 10.5 d. At 37⁰C Vmax increases to 8.5 g l^{- 1} h^{- I} but the half-life is reduced to 2.3 d. The average downtime between batch reactions is 28 h. calculate the reactor volume required to produce 5000 tonnes of aspartic acid per year

You perform the three different two-factor crosses (Cross 1: XY and xy, Cross 2: YZ and yz, and Cross 3: XZ and xz). Assume all crosses are between diploid flies homozygous for the alleles of these genes. You observe 7% recombinants in the first cross, 20% recombinants in the second cross, and 13% recombinants in the third cross. if cross between XyZ and xYz leads to which of the followining recombinant with double cross over .
