A)Bacterium BB acquired degradative and virulence plasmids by horizontal gene transfer
B)Bacterium BB picked up fertility and Col-plasmids via conjugation
C)Bacterium BB was exposed to a bacteriophage which is now in its lytic phase
D)Bacterium BB was transformed with a resistance plasmid and a digestive plasmid
E)Bacterium BB sexually reproduced with another strain of bacteria that had both toluene-degrading gene and virulence gene

A)both are composed of DNA packaged in the nucleus
B)both are composed of double-stranded DNA
C)both are composed of circular chromosomes
D)both are composed of multiple,linear chromosomes
E)both contain chromosome with a single origin of replication

A)bacteria can acquire genetic material from each other.
B)bacteria do not release DNA into the environment for other bacteria to take up.
C)bacteria must be in physical contact in order for bacteria to exchange genetic material.
D)the genetic transfer occurred when the bio+,met+ phe-thr- strain transferred DNA to the bio-met- strain.
E)All of these observations were made by Lederberg and Tatum.
