(B) Green Revolution

(C) Gene Therapy

(D) His work in Ecology

3 questions are suggested by Mr. Sahil Ahmed







1. (B) Well Born



2. (A) Golgi to ER

        KDEL Sequence is present in carboxy terminal use to retrieve material from Golgi to ER.


3. (B) 11

        10.7 Base pair per turn is in A-DNA.


4. (C) 48 (more then human)

        Number of Chromosome is not related with evolution


5. (D) Mutualism



6. (C) Neoschizomers



7. (A) YAC (Yeast Artificial Chromosome)



8. (D) Pyrosequencing

        Pyrosequencing is the fastest DNA Sequencing method which does not require electrophoresis or any fragment separation method. Any method can be Automated, there is no separate method like Automated DNA Sequencing.


9. (D) Length of mRNA



10. (A) DNA finger printing
