Back (Answer)

polyphyletic

Front (Question)

what was a sign of cross over

Back (Answer)

spores that were not 4 black then 4 white (a mix of black and white) were recombinant

#10

Front (Question)

the uptake of foreign DNA into the genome from the surrounding environment

Back (Answer)

transformation

#11

Front (Question)

using plasmids to move DNA from one cell to another

Back (Answer)

transformation

#12

Front (Question)

role of sulfuric acid in the enzyme lab

Back (Answer)

denatures the enzyme’s active site because of the low pH

#13

Front (Question)

calculate rf value

Back (Answer)

distance traveled by component/ (divided by) distance traveled by the solvent

#14

Front (Question)

can environmental factors alter gene expression?

Back (Answer)

YES this is what the lac operon is! having lactose in the environment induces it

#15

Front (Question)

rf value cannot be greater than
