A) the Novel

Multiple Choice

Assume that a new low-calorie sweetener is developed.The structure is novel and is tested with the Ames test for mutagenicity.The following results are obtained: $$\begin{array} { | l | l | } \hline \text { Sample } & \text { Number of his } { } ^ { + } \text {Revertent Colonies } \\\hline \text { Distilled water } & 2 \\\hline \text { Distilled water + rat liver enzymes } & 3 \\\hline \text { Sweetener } & 6 \\\hline \text { Sweetener + rat liver enzymes } & 65 \\\hline\end{array}$$
What conclusion is most consistent with these data?

A) The sweetener is not mutagenic.
B) Rat liver enzymes are highly mutagenic.
C) The sweetener is not mutagenic but can be converted into strong mutagens.
D) The sweetener is mutagenic and can be converted into strong mutagens.
E) The sweetener and its conversion products are equally mutagenic.
