Show Answer

Answer:

Correct Answer: A

Solution:

[a] Hirudin is a protein that prevents blood clotting.

The gene encoding hirudin was chemically synthesised.

This gene was then transferred into Brassica napus, where hirudin accumulates in seeds.

Hirudin is purified and used as medicine.

In this case, the transgene product itself is the product of interest.
