Question

40 multiple choice 1 point which of the following is used as a selectable marker in your pblu transformation? lb agar plates competent bacterial cells beta - galactosidase 37 degrees incubator

Explanation:

In pBLU transformation, a selectable marker helps identify transformed cells. Beta - galactosidase (encoded by the lacZ gene in pBLU) is used as a selectable (and screenable) marker, often via the blue - white screening method. LB agar plates are a growth medium, competent bacterial cells are the cells being transformed, and a 37 - degree incubator is for incubation, not a selectable marker.

Answer:

C. Beta - galactosidase
