question 26

Multiple Choice

Use the following information when answering the corresponding question(s) .
Shu-ichi Nakano reported in Science in February 2000 that "The RNA enzyme (ribozyme) from hepatitis delta virus catalyzes self-cleavage of a ...[chemical] ...bond." This reaction is inherently slow due to the formation of an unfavorable negative charge on the ribozyme.The author goes on to show that this self-cleavage is made faster by joining it with an acid-base reaction that neutralizes the negative charge.Nakano's model describes a positively charged cytosine base on the ribozyme acting as the acid,and magnesium hydroxide acting as the base.Specifically,the cytosine donates its proton (H⁺) to neutralize the unstable negative charge that would have formed on the ribozyme.
-Refer to Nakano's quote from Science.If the cytosine is positively charged (+) before self-cleavage,what would its charge be after self-cleavage?
