part a
plasmid dna samples are taken from four bacteria species and treated with the same
restriction enzyme. the treated dna is then analyzed using gel electrophoresis. the results of
the gel electrophoresis are shown in the diagram.

which species has the most restriction enzyme recognition sites in its dna?
oa
ob
oc
od

Explanation:

Gel electrophoresis separates DNA fragments. More restriction enzyme recognition sites lead to more DNA fragments. Species C has the most bands (fragments) on the gel.

Answer:

C.
