19. Stanley Cohen had been studying small ringlets of DNA called plasmids.

20. RNAi involves silencing of all mRNA due to a complementary dsRNA molecule that binds to and prevents transcription of the mRNA (silencing).

21. DNAi takes place in some of the eukaryotic organisms as a method of cellular defence.

22. Ampicillin sensitive gene in a plasmid could be considered as useful selectable markers for E. coli.

23. GM plants have been useful in decreasing crop yields.

24. Indian Government has set up organisations such as GEAC (Genetic Engineering Approval Committee), which will make decisions regarding the validity of GM research and the safety of introducing GM-organisms for public services.

25. Transgenic animals produce some biological products that are attempted to cure PKU.

26. RNAi involves silencing of a specific mRNA due to a complementary dsRNA molecule that binds to and prevents translation of the mRNA (silencing).
