Question

Hirudin gene inserted in Brassica napus was?

• A. Synthesised chemically
• B. Obtained from leech
• C. Got from Bacillus thuringiensis
• D. Brassica campestris

Answer 1

The correct option is A Synthesised chemically

Hirudin is a potent thrombin inhibitor originally derived from the leech. Unlike heparin, hirudin act directly on thrombin, rather than through other clotting factors. It is difficult to extract large amounts of hirudin from natural sources, so a method for producing and purifying this protein using recombinant biotechnology has been developed. This has led to the development and marketing of a number of hirudin-based anticoagulant pharmaceutical products. Hence, the gene inserted in Brassica napus was synthesized chemically using recombinant technology.

So, the correct option is 'Synthesised chemically'.
