Golden rice is a genetically modified crop plant where the incorporated gene is meant for the biosynthesis of:

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

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

1. alleviation of vitamin-A deficiency

2. pest resistance

3. herbicide tolerance

4. producing a petrol-like fuel from rice

Microbes found to be very useful in genetic engineering are:

1. Escherichia coli and Agrobacterium tumefaciens

2. Vibrio cholerae and a tailed bacteriophage

3. Diplococcus sp. and Pseudomonas sp.

4. Crown gall bacterium and caenorhabditis elegans
