Question

Hirudin is

• A. a protein produced by Hordeum vulgare, which is rich in lysine
  
• B. a toxic molecule isolated from Gossypium hirsutum, which reduces human fertility
• C. a protein produced from transgenic Brassica napus which prevents blood clotting
  
• D. an antibiotic produced by a genetically engineered bacterium Escherichia coli

Answer 1

The correct option is C a protein produced from transgenic Brassica napus which prevents blood clotting


Hirudin is a protein that stops blood clotting. The gene encoding hirudin was chemically synthesized. This gene was then transferred into Brassica napus, where hirudin accumulates in seeds. The hirudin is purified and used as medicine.
A topical cream manufactured from hirudin is used to shrink hematomas caused by musculoskeletal injuries.
