#Part-A Aptitude & General Biotechnology
  1. It is possible to incorporate the reagents in a lipid drop
  2. It refers to the PCR carried out at large scale
  3. The temperature variation is not possible easily
  4. If there is a single template molecule at the start then amplification results in the mixture and it because of the extent of extension carried out

A cylindrical stirred bioreactor of diameter and height 2 m has a Rushton turbine one-third the tank diameter in size. The bioreactor contains Newtonian culture broth with the same density as water and with viscosity 4 cP. The tank is now aerated. In the presence of gas bubbles, the approximate relationship between ungassed power number (NP)0 and gassed power number (NP)g is: (NP)g =0.5 (NP)0. What maximum stirrer speed is now possible in the sparged reactor? Estimate the mixing time.
