To protect tobacco plants against Meloidegyne incognita using RNAi, nematode specific genes were introduced in the plant using:

1. Transposons

2. Retrotransposons

3. Virus with RNA genome 

4. Agrobacterium

A permanent cure for ADA deficiency could be:

Polymerase Chain Reaction is not used in :

1. Confirming presence of a pathogen during early infection

2. Identifying the mutated genes in suspected cancer patients

3. Isolating the gene of interest from host DNA to be cloned by recombinant procedures

4. Detection of the presence of HIV in suspected AIDS patient

If gene isolate from marrow cells producing ADA is introduced into cells at early embryonic stage, it could be a permanant cure of ADA deficiency because the early embryonic cells :

1. Are more differentiated than the later stage cells

2. Are constantly dividing and do not get differentiated 

3. Are easy to manipulate than the later stage cells

4. Are virtually immortal
