Ques. 1AIPMT 2008

A transgenic food crop which may help in solving the problem of night blindness in developing countries is

  1. Flavr Savr tomatoes
  2. Bt soybean
  3. Starlink maize
  4. Golden rice

Answer

(4) Golden rice

Solution

Night blindness is caused by deficiency of vitamin A.

Golden rice is a genetically modified rice that produces β-carotene (provitamin A) in its grains, which the body converts into vitamin A.

Flavr Savr tomato has delayed ripening, while Bt soybean and Starlink maize carry insect-resistance (Bt) genes.

∴ Golden rice can help solve the problem of night blindness.
