The ability to integrate its own DNA into the host's DNA makes it possible to transfer the integrated DNA to another organism
B
The ability to utilize the hosts' protein synthesis machinery where copies of synthesized proteins remain stored
C
The ability to only infect a limited range of hosts helps to transfer genetic material more efficiently.
