Question

Desired genes have been introduced into transgenic animals to obtain large scale production of useful biological products encoded by these genes. This approach is generally referred to as

• A. Hybridoma technology
• B. Molecular farming
• C. Gene therapy
• D. Down stream processing

Answer 1

The correct option is B Molecular farming

A. Hybridoma technology is the production of monoclonal antibodies. Monoclonal antibodies are made outside the body by hybrid cells culture known as hybridomas. For producing monoclonal antibodies, B- cells are removed from the spleen of an animal which are then fused with myeloma tumour cells that can grow indefinitely in cultures. (Myeloma is the cancer of B- cells).

B. Molecular farming is an application of genetic engineering in which desired genes from human or animal origin are introduced into plants or animals for getting cost effective production of therapeutic products such as hormones, recombinant vaccines, antibodies etc.

C. Gene therapy means altering the genotype of a cell or tissue or even whole organism to correct a genetic disorder, by placing normal gene in place of defective or malfunctioned gene.

D. Downstream processing is the stages of separation and purification of products obtained after fermentation or any other biotechnological process.

So, the correct answer is 'Molecular farming'.
