Integration of linear transforming DNA into the chromosome
A. is not required for the expression for the transformed genes.
B. is catalyzed by the RecA gene.
C. almost never occurs because restriction endonuclease will degrade the DNA before it is integrated.
D. only occurs in laboratory-based systems in artificial competent cells.
