Question

Golden rice is a transgenic crop of the future with the following improved trait
A. High lysine (essential amino acid) content
B. Insect resistance
C. High Protein content
D. High vitamin-A content

Answer 1

Hint: A transgenic crop is an organism that has been genetically modified (GMO). Transgenic means that genes have been transferred using recombinant DNA technology. A transgenic crop typically contains one or more genes that have been artificially inserted from an unrelated plant or from a different species entirely.

Complete step by step solution:
Rice is a staple food crop for more than half of the world's population, providing 30-72 percent of energy intake in Asian countries and serving as an important food crop for aimed vitamin deficiencies. Crops are modified with supplementary nutritional values using genetic modification technologies to improve people's survival.

Golden rice is a new genetically altered rice (Oryza sativa) variety. It is created during the synthesis of vitamin A in order to biosynthesize beta-carotene. It contains a lot of vitamin A. Peter Beyer created the design. So the rice grains (seeds) are yellow due to carotene, the rice is commonly known as golden rice.
Its goal is to create a fortified food that can be grown and ingested in areas where dietary vitamin A is scarce, a deficiency that is estimated to kill 670,000 children under the age of five every year and end up causing an extra 500,000 cases of permanent childhood blindness.
It consists of nearly 5% of lysine content, 6% of insect resistance, 12% of high protein content, and 77% of high vitamin-A content.

Hence, the correct option is D.

Note:
Golden rice is rice that has been fortified with vitamin A, has a daffodil gene, and is high in carotene. In humans, beta-carotene deduced from Golden Rice is effectively transformed into vitamin A. Golden rice varies from its parental strain in that it contains three genes for beta-carotene biosynthesis. The parental strain will naturally produce beta-carotene in their leaves, where it is engaged in photosynthesis. In the endosperm, where photosynthesis does not occur, the pigment is usually absent.
