Question:

Select the correct statements from the following :

A-Plants, bacteria, fungi and animals whose genes have been altered by manipulation are called Genetically Modified Organisms (GMO).

B-Examples of lepidopterans are tobacco budworm, armyworm.

C-Golden rice is Vitamin ‘A’ enriched rice.

D-Gene therapy is the insertion of genes into an individual’s cells and tissues to treat diseases especially hereditary diseases.

Choose the correct answer from the given options.

Options:

A and B only

B , C and D only

A,B ,C and D

A, C and D

Correct Answer:

A,B ,C and D

Explanation:

The correct answer is Option (3) – A,B ,C and D

1-Lepidopterans (tobacco budworm, armyworm), coleopterans (beetles) and dipterans (flies, mosquitoes).

2. Plants, bacteria, fungi and animals whose genes have been altered by manipulation are called Genetically Modified Organisms (GMO).

3-Genetic modification has enhanced nutritional value of food, e.g., golden rice, i.e., Vitamin ‘A’ enriched rice.

4-Gene therapy is the insertion of genes into an individual’s cells and tissues to treat diseases especially hereditary diseases. It does so by replacing a defective mutant allele with a functional one or gene targeting which involves gene amplification.
