Golden rice is a promising transgenic crop. When released for cultivation, it will help in

  1. Herbicide tolerance

  2. Producing a petrol-like fuel fro m rice

  3. Alleviation of vitamin A deficie ncy

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

Golden rice is specifically engineered to contain beta-carotene, which helps combat Vitamin A deficiency in populations that rely heavily on rice as a staple food.

Consumption of which one of the following foods can prevent the kind of blindness associated with vitamin 'A' deficiency?

  1. Falver Savr' tomato

  2. Canolla

  3. Golden rice

  4. Bt-Brinjal
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Golden rice is a variety of Oryza sativa rice produced through genetic to biosynthesize beta-carotene, a precursor of vitamin-A in the edible part of rice. The research that led to golden rice was conducted with the goal of helping children who suffer from vitamin A.

So, the correct option is 'Golden rice'.

C Correct answer
Explanation

The principle of developing transgenic plants and animals is to introduce the gene of interest into the nucleus to germ cell.

So, the correct option is 'Germ cell'.

Which one of the following bacteria is used for production of transgenic plants?

  1. Escherichia coli

  2. Bacillus thuringiensis

  3. Staphylococcus aureus

  4. Agrobacterium tumefaciens
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Bt corn varieties, for example, contain a gene from a bacterium found in the soil that causes the transgenic corn to produce an insecticidal protein.

So, the correct option is 'Bacillus thuringiensis'.

RNA interference which is employed in making tobacco plant resistant to Meloidegyne incognita is essentially involved in

  1. preventing the process of replication of DNA

  2. preventing the process of translation of mRNA

  3. preventing the process of splicing of hnRNA

  4. preventing the process of transcription
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

RNA interference is a gene-silencing process that blocks the expression of genes in the parasite when it enters the host's body.RNA is a method adopted to prevent infestation of roots of tobacco plants by a nematode Meloidogyne incognita. In RNA, a complementary RNA binds to mRNA to form a ds RNA that cannot translate and hence, its expression is blocked.

So, the correct option is 'Preventing the process of translation of mRNA'.

Golden rice is a transgenic crop of the future with the following improved trail

  1. insect resistance

  2. high lysine (essential amino acid) content

  3. high protein content

  4. high vitamin-A content
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Golden rice is a genetically modified variety of rice engineered to produce beta-carotene, which is a precursor to Vitamin A, to address Vitamin A deficiency.
