What is a heterologous host?

Options

  1. AA host that is not suited for producing a desirable protein
  2. BA host that is used for expressing foreign genes
  3. CA host that is not compatible with the gene of interest
  4. DA host that is not capable of producing the target protein

Correct answer

B. A host that is used for expressing foreign genes

Step-by-step solution

After having cloned the gene of interest and having optimized the conditions to induce the expression of the target protein, one has to consider producing it on a large scale. If any protein encoding gene is expressed in a heterologous host, it is called a recombinant protein . The cells harbouring cloned genes of interest may be grown on a small scale in the laboratory. The cultures may be used for extracting the desired protein and then purifying it by using different separation techniques
