A, B and C are transformed host cells with r-DNA made up of pBR322. A has foreign DNA inserted at BamH1 site, B has foreign DNA inserted at PvuII and C has DNA inserted in LacZ. When they are grown on media for selection which of the following changes observed are incorrect.
A) C transformant produces blue coloured colonies
B) C transformant colonies do not produce blue colour
C) A transformant survive on the medium containing ampicillin and B survive on tetracycline containing medium
D) Due to insertional inactivation, A survive on tetracycline containing medium and B survive on medium with ampicillin.
