Which statement is TRUE regarding the process catalyzed by the bacteriophage $\lambda$ integrase?

Question

Quizplus · Accepted Answer

The process catalyzed by the bacteriophage F1F1F1S1F1F1F10 integrase involves successive transesterifications, as it involves the formation and breaking of phosphodiester bonds between the nucleic acids. This is characteristic of integrase enzymes, which mediate the integration of foreign DNA into the host genome. The reaction is not ATP-dependent (choice B), instead it is mediated by nucleophilic attack by the catalytic serine residues in the active site of the integrase (choice A). The integrase is not a hydrolase (choice D) as it does not catalyze the hydrolysis of water to break bonds. Finally, the integrase has a specific target DNA sequence (choice E), which is recognized by the protein and serves as the site of integration.
