Which of the following is true for Golden rice?

1.	It has yellow grains, because of gene introduced from a primitive variety of rice
2.	It is Vitamin A enriched, with a gene from daffodil
3.	It is pest resistant, with a gene from Bacillus thuringiensis
4.	It is drought tolerant, developed using Agrobacterium vector

Why does Bt toxin not kill Bacillus thuringiensis?
1. The bacillus keeps proteins in inclusions
2. The toxin exists in the bacillus as a pro-toxin
3. The bacillus protects its genetic material by methylation
4. The bacillus has a tough cell wall of peptidoglycan

Cotton plants can be protected from corn borer by the proteins coded by:
1. cryIAc                       2. cryIIAb
3. cryIAb                       4. cryIAd

RNAi, as a mechanism of cellular defense, takes place in:
1. All bacteria

2. All unicellular organisms

3. All plants only

4. All eukaryotic organisms

How were nematode-specific genes introduced in tobacco plants?

1. Using page DNA

2. Using a retrovirus

3. By gene gun
