What is the role of bacterial, plant or animal cells in recombinant technologies?

Options

  1. ATo extract the desired protein
  2. BTo express the foreign gene
  3. CTo produce a desirable protein
  4. DTo purify the desired protein

Correct answer

B. To express the foreign gene

Step-by-step solution

When you insert a piece of alien DNA into a cloning vector and transfer it into a bacterial, plant or animal cell, th e alien DNA gets multiplied. In almost all recombinant technologies, t he ultimate aim is to produce a desirable protein . Hence, there is a need for the recombinant DNA to be expressed. The foreign gene gets expressed under appropriate conditions. The expression of foreign genes in host cells involve understanding many technical details.
