A wheat variety, Atlas 66, which has been used as a donor for improving cultivated wheat is rich in ___________.

  1. Iron

  2. Carbohydrates

  3. Proteins

  4. Vitamins
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Atlas 66 is a famous wheat variety developed through biofortification specifically to increase protein content. It has been widely used in breeding programs to improve the nutritional value of wheat.

Biofortification refers to the development of crop plants which are ______________.

  1. Resistant to disease

  2. Resistant to insect pests

  3. Having improved nutritional quality

  4. Having improved iron content
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Biofortification is the process of increasing the nutritional value of crops through selective breeding or genetic engineering. While it can involve iron, the term broadly refers to improving overall nutritional quality.

Select the correct statement regarding an improved variety of transgenic basmati rice. i.e. golden rice.

  1. It does not require the use of chemical fertilisers

  2. It is completely resistant to all insect pests and diseases

  3. It gives high yields but not characteristic aroma

  4. It gives high yields and rich in vitamin A
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

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 synthesizing 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 the yellow colour of rice grains due to the presence of β-carotene.

So, the correct answer is 'It gives high yields and rich in vitamin A'.

The scientific process by which crop plants are enriched with certain desirable nutrient is called

  1. Crop protection

  2. Breeding

  3. Bio-fortification

  4. Bio-remediation
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Bio-fortification is the specific scientific method used to increase the concentration of vitamins and minerals in crops. It is distinct from crop protection or remediation.

Which of the following nutritional quality can be improved by biofortification?

  1. Protein quality

  2. Oil content quality

  3. Vitamin content

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Biofortification is the method in which the food is added or supplemented with the required nutrients. It is a process of breeding crops with higher levels of vitamins, minerals, proteins, and fat content. The new varieties of legume plants can be developed through hybridization to produce more amount of proteins in the seeds. The plants whose seeds are used for the extraction of oil can be fortified to produce more oil. The staple crops like rice can be fortified to produce beta-carotene which is the precursor form of vitamin A. 

Thus, the correct answer is option D.

Beta-carotene can be induced in the golden rice by a process known as

  1. Biological nitrogen fixation

  2. Biofortification

  3. Bioremediation

  4. All of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Biofortification is the method in which the food is added or supplemented with the required nutrients. The staple crop like rice is fortified to produce the precursor of vitamin A. Golden rice is the transgenic rice in which beta-carotene synthesizing gene psy and crtl are incorporated by the help of genetic engineering. Beta-carotene is the precursor of the vitamin A. The consumption of the golden rice can help to prevent the deficiency disorders due to less intake of vitamin A. 

Thus, the correct answer is option B.

Breeding crops for improved nutritional quality is referred to as

  1. Biome

  2. Biomagnification

  3. Biomining

  4. Biofortification

  5. Bioremediation
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Bio fortification is the process of enriching the nutrient content and the quantity and quality of vitamins, minerals, carbohydrate proteins and fats in crops. Eg.- vitamin A enriched rice, golden rice, etc.

Which of the following technique can fill the deficiency of micronutrients?

  1. Biological nitrogen fixation

  2. Biofortification

  3. Bioremediation

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Biofortification is the method in which the food is added or supplemented with the required nutrients. It is a process of breeding crops with higher levels of vitamins, minerals, proteins, and fat content. The micronutrients are not present in every type of food and results in the deficiency diseases. The plants can be developed to produce the micronutrients through hybridization or selective breeding. These foods can be helpful to prevent deficiency disorders. 

Thus, the correct answer is option B.

Bread fortified with folate can help in 

  1. Bone development

  2. Neurological development

  3. Fetal development

  4. Both B and C
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Biofortification is the method in which the food is added or supplemented with the required nutrients. It is a process of breeding crops with higher levels of vitamins, minerals, proteins, and fat content. The folate is responsible for the spinal cord development and development of the brain. An adequate amount of folate taken by the pregnant women prevents the chances of neural tube defects in the foetus. 

Thus, the correct answer is option D.
