Consider three yellow, round peas, labeled A, B, and C. Each was grown into a plant and crossed to a plant grown from a green, wrinkled pea. Exactly 100 peas issuing from each cross were sorted into phenotypic classes as follows

A:        51 yellow, round

            49 green, round

B:      100 yellow, round

C:  24 yellow, round

      26 yellow, wrinkled

      25 green, round

      25 green, wrinkled

What were the genotypes of A, B, and C respectively?

Dynamic programming determines optimal alignment by matching two sequences for all possible pairs of characters between the two sequences.

Reason(R): Use of the dynamic programming method requires a scoring system to account for matches and mismatches between sequences, and a scheme for Gap penalties.

A genetically-engineered strain of yeast is cultured in a bioreactor at 30⁰C for production of heterologous protein. The oxygen requirement is 80 mmol 1-1 h-I; the critical oxygen concentration is 0.004 mM. The solubility of oxygen in the fermentation broth is estimated to be 10% lower than in water due to solute effects. What mass-transfer coefficient is required if pure oxygen is used instead of air?
