Table $ 8.1 $
Culture 1: $ \mathrm{F}^{+} $, leucine $ { }^{+} $, histidine $ { }^{+} $
Culture 2: $ \mathrm{F}^{-} $, leucine- , histidine-
-In Table 8.1,what will be the result of conjugation between cultures 1 and 2 (reminder: F+ has a different meaning than Hfr)?
A)1 will remain the same; 2 will become F⁺,leucine⁻,histidine⁻
B)1 will become F⁻,leu⁺,his⁺; 2 will become F⁺,leu⁻,his⁻
C)1 will become F⁻,leu⁻,his⁻; 2 will remain the same
D)1 will remain the same; 2 will become F⁺,leu⁺,his⁺
E)1 will remain the same; 2 will become F⁺ and recombination may occur

In bacterial conjugation, the F⁺ (fertility factor positive) cell can transfer the F plasmid to an F⁻ (fertility factor negative) cell, converting it to F⁺. The F⁺ cell remains unchanged, while the F⁻ cell gains the F plasmid but does not necessarily receive other genetic traits like leucine or histidine production capability.
