Which of the following explains why production of transgenic plants is easier than production of transgenic animals?
1. Plant cells can grow in cell culture.
2. Plant cells have a lower number of potentially lethal genes.
3. Plant cells are totipotent.
4. Production of mutant plants poses less ethical dilemmas than production of mutant animals.

Plants are more easily manipulated by genetic engineering than are animals because:

1. Plant genes do not contain introns

2. More vectors are available to transfer rDNA into plant cells

3. Totipotency is a feature generally associated with plant cells and not with animal cells

4. Genes can be inserted into animal cells by microinjection.

If the goal were to create a plant resistant to an insecticide, which cell-based plant technology would be most effective ?

(1) clonal propagation

(2) cybridization

(3) protoplast fusion

(4) mutant selection

A genetically engineered micro-organism used successfully in bioremediation of oil spills is a species of:

(1) Pseudomonas

(2) Trichoderma

(3) Xanthomonas

(4) Bacillus

A transgenic food crop, which may help in solving the problem of night blindness in developing countries is:

1. Flavr savr tomatoes

2. Starlink maize

3. Bt soybean

4. Golden rice

Main objective of production / use of herbicide resistant GM crops is to 

(1) eliminate weeds from the field without the use of manual labour

(2) eliminate weeds from the field without the use of herbicides

(3) encourage eco-friendly herbicides

(4) reduce herbicide accumulation in food particles for health safety

The foreign gene in a transgenic plant may be derived from

(1) an insect 

(2) an animal

(3) a bacteria 

(4) all of these.

Genetically modified (GM) crops can be produced by

(1) recombinant DNA technology

(2) somatic hybridization

(3) cross breeding

(4) micropropagation

Three critical research areas of biotechnology are:

I. Providing the best catalyst in the form of improved organism usually a microbe or pure enzyme

II. Multiple Ovulation Transfer Technology (MOET)

III. Creating optimal conditions through engineering for a catalyst to act.

IV. Downstream processing technologies

(1) I, II, III, IV      

(2) I, III, IV          

(3) I, II                 

(4) II and IV

Which of the following is correct?

(1) The procedure for chemical safety testing / toxicity is the same as that used for testing toxicity of drugs

(2) Transgenic animals are more sensitive to the toxic substances than non-transgenic animals

(3)  Golden rice, a genetically engineered rice has high vitamin A (β-carotene) content

(4) All are correct
