6. What do you understand by the term “co-transformation”?
a) Integration of 2 transgenes
b) Integration of similar transgenes
c) Integration of a group of transgenes
d) Integration of chromosomal DNA
View Answer

Answer: a
Explanation: The transfection with two physically unlinked DNAs results in co-transformation that is the integration of both the transgenes into the genome.

7. Southern blot hybridization is done for testing the presence of _________ in selection of transformants.
a) Non-selected DNA
b) Selected plasmid DNA
c) Genomic DNA
d) Selected genomic DNA
View Answer

Answer: a
Explanation: To obtain co-transformants, cells were transfected with HSV Tk gene and well defined plasmid DNA. Cells selected on HAT medium are then tested by southern blotting for the presence of non-selected DNA.

8. Incorporation of ribozymes into antisense RNA leads to their __________
a) Activity
b) Temperature change
c) Cleavage
d) Regeneration
View Answer

Answer: c
Explanation: The incorporation of ribozyme catalytic centers into antisense RNA allows the ribozyme to be particularly targeted and then cleaved and degraded.
