Question

Fortified maize hybrids with double the amount of _____________amino acids were produced in 2000.

• A. thiamine and riboflavin
• B. lysine and tryptophan
• C. fructose and lactose
• D. lysine and thiamine

Answer 1

The correct option is B lysine and tryptophan

Biofortification is the process of breeding nutrient rich crops with higher levels of vitamins, minerals, fats, proteins, etc. with the idea to improve public health.

A protein rich, hybrid maize variety was developed in 2000, which had twice the amounts of the amino acids lysine and tryptophan compared to the existing maize hybrids.

Thiamine and riboflavin are vitamins. Fructose is a simple sugar (monosaccharide) found naturally in fruits and lactose is a sugar (disaccharide) found in milk.
