RNAi is a mechanism to silence genes with the help of
1. ssRNA
2. dsRNA
3. ssDNA
4. dsDNA
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:
1. Enzyme replacement therapy
2. Bone marrow transplant
3. Introduction of a functional ADA cDNA into lymphocytes
4. Introduction of gene isolated from marrow cells producing ADA into early embryonic cells
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

(1) clonal propagation
(2) cybridization
(3) protoplast fusion
(4) mutant selection
Which protein has been produced generating a transgenic sheep that is used for replacement therapy for individuals at risk from emphysema?
1. Plasminogen activator (rPA)
2. α-antitrypsin (ATT)
3. Casein
4. Amyloid precursor proteins
Consider the following statements :
I. The BCG vaccine is given as a protection against Tuberculosis
II. Oral polio vaccine is being used in the Pulse Polio Immunization programme in India
III. Hepatitis B vaccine is made with the help of recombinant E.Coli
Which of the above statements are true ?
1. I and II only
2. I and III only
3. II and III only
