Question
In genetic engineering, the antibiotics are used
-
as selectable markers
-
to select healthy vectors
-
as sequences from where replicaton starts
-
to keep the cultures free of infection
Solution
B.
to select healthy vectors
The integration of selectable marker gene along with a gene of interest is helpful for identifying transformed cells. However, the presence of selectable marker for antibiotic resistance in a genetically modified organism that is released into environment is not desirable.
