71. Conjugation between a bacterium that lacks an F factor (F) and a bacterium that has an F factor on its chromosome (F+) would typically produce which of the following results?
(A) The F bacterium ends up carrying one or more plasmids from the F+ bacterium; and the F+ bacterium that lacks those plasmids. 
(B) The F+ bacterium ends up with a recombinant chromosome that carries some genes from the F bacterium, and the F bacterium ends up with an unaltered chromosome.
(C) The F+ bacterium ends up with a recombinant chromosome that carries some genes from the F bacterium, and the F-bacterium ends up with a chromosome that lacks those genes. 
(D) The F bacterium ends up with a recombinant chromosome that carries some genes from the F+ bacterium, and the F+ bacterium ends up with an unaltered chromosome. 
(E) The Fbacterium ends up with a recombinant chromosome that carries some genes from the F+ bacterium, and the F+ bacterium ends up with a chromosome that lacks those genes.
