|
|
genetic engineering
|
|
|
selective breeding
|
|
|
gene therapy
|
|
|
CRISPR

Explanation:
Detailed explanation-1: -Golden rice improves vitamin A intake and may reduce vitamin A deficiency among women and children. Food derived from golden rice varieties is as safe as food derived from conventional rice varieties.
Detailed explanation-2: -Golden rice was created by modifying the rice genome to include a gene from the daffodil Narcissus pseudonarcissus that produces an enzyme known as phyotene synthase and a gene from the bacterium Erwinia uredovora that produces an enzyme called phyotene desaturase.
Detailed explanation-3: -Nutritional value This genetically modified rice is capable of producing beta-carotene in the endosperm (grain) which is a precursor for vitamin A.
