Question

Golden rice is yellow in colour due to the presence of

• A. Riboflavins
• B. $\beta$-carotene
• C. Vitamin $B_1$
• D. Complex genetic material

Answer 1

The correct option is B $\beta$-carotene

Rice is a staple food in many countries, particularly in Asia, but does not contain vitamin A or its immediate precursors. By inserting two genes from Daffodil and one gene from a bacterial species into rice plants, Swiss researchers have produce rice capable of synthesising β-carotene, the precursor of vitamin A. Vitamin A is required by all individuals as it is present in retina of eyes. Deficiency of vitamin A causes night blindness and skin disorders. This rice is called 'Golden rice' because of yellow colour of rice grains due to the presence of β-carotene.

So, the correct answer is 'β-carotene'.
