Q.Write any two scientific and commercial values of transgenic animals in favour of human being.

Transgenic animals produce pharmaceuticals in milk and serve as research models/improved livestock.

Transgenic animals — animals carrying an artificially inserted foreign gene — have both scientific and commercial value for humans. Scientific value: they serve as valuable model organisms for studying human gene function and the progression of diseases, and for testing the safety and efficacy of new drugs and vaccines before human trials, reducing risk and cost. Commercial value: certain transgenic animals, such as cows or goats engineered with human genes, can secrete valuable therapeutic proteins — such as human insulin, blood clotting factors, or antibodies — directly in their milk, providing an efficient, large-scale, low-cost production system for these biopharmaceuticals ('molecular pharming'); transgenic livestock can also be d …
