The gene of interest is inserted into transfer vector and then further into viral genome leading to the formation of modified virus. How can plaques from modified virus differentiated from plaques from wild-type virus?
(a) Chemically
(b) Visually
(c) On the basis of magnetic properties
(d) On the basis of longeitivity of plaques
The question was posed to me in an interview for internship.
My query is from Cultured Cells And Bacillovirus in division Using Other Organisms of Genetic Engineering
