Verified By Collegedunia

The Correct Option is C

Solution and Explanation

Transgenic plants are those plants in which a foreign gene has been introduced and stably integrated into the host DNA. A gene that is transferred using the tools of molecular biology is called transgene. Brassica napas is one of the transgenic plant species. Recently transgenic plants have been explored for production of biologically active peptides and proteins having pharmaceutical applications including use as blood proteins, enzymes, growth, hormones etc. The protein hirudin present in leech, prevents blood clotting. The gene was chemically synthesized and introduced in Brassica napas and later on the seeds contained the protein.

Notes on Applications of Biotechnology

Concepts Used:

Applications of Biotechnology

Biotechnology is the technology that utilizes biological systems, living organisms, or parts of this to develop or create different products.

For example, brewing and baking bread fall within the concept of biotechnology (use of yeast (= living organism) to produce the desired product).

Agriculture

Alternative to conventional farming: A possible solution is the use of genetically modified crops which is an alternative path to conventional farming.

Medicine

In the area of healthcare, recombinant DNA technological processes have made an immense impact which enables the mass production of safe and more effective therapeutic drugs.

Gene Therapy

A collection of methods that allows the correction of a gene defect that has been diagnosed in a child/embryo is called Gene Therapy.

CRISPR technology

For editing genomes, CRISPR is a simple yet powerful tool which allows researchers to easily alter DNA sequences and modify gene function.
