Question

A transgenic rice ( golden rice) has been developed for increased content of
A. Vitamin- A
B. Vitamin-B1
C. Vitamin -C
D. Vitamin-D

Answer 1

Hint:- Transgenic plant and animal varieties are founded .These are also called genetically modified organisms (GMO). These are modified to accumulate the new characters which the organism doesn’t have before and these are useful to mankind. These modifications don’t cause any ill effects on the public & organisms which are exposed to modification.

Complete solution:
● Rice is a source of protein and various vitamins thiamine, niacin, and various minerals of phosphorus etc.
● Golden rice contains those vitamins, minerals, and vitamins which is the high content of Vitamin-A which prevents night blindness in people
● Vitamin-A: Transgenic rice contains vitamin -A which is a major source for it. It is produced through genetic engineering to biosynthesize beta- carotene a precursor of vitamin-A.
● Vitamin-B1: It is also present in the rice compared to a lesser quantity of vitamin-A .it is richly present in green & leafy vegetables. Compared to golden rice.
● Vitamin-C: It presents very minutely or absent in the golden rice. Vitamin-C is a rich source of bitter gourd, mustard, and tomato. Mainly vitamin-C high in citrus fruits.
● Vitamin-D: It is also the same as vitamin-C. Generally, a rich source of vitamin-D is sunlight during morning & evening hours. Fish liver oil, cod liver oil.
So, the correct answer is option A.

Note:- Transgenic rice contains vitamin-A. Contains up to 35micro micrograms carotene per gram of golden rice. It is important to determine vitamin-A equivalency of Rice beta carotene to project the potential effort of this biofortified grain in the rice consuming population that commonly exhibit low vitamin-A status. These are to obtain better yield and are resistant to harsh environmental conditions.
