1. The lambda phage is largely incapable of infecting bacterial species other than E. coli. This is most likely because:

    1. E. coli has a circular chromosome while other bacterial species do not.
    2. other bacterial species have circular chromosomes while E. coli does not.
    3. other bacterial species lack a chromosomal integration site for lambda DNA.
    4. other bacterial species lack specific cell surface proteins that lambda normally binds.
