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.
-Which of the following chemical bonds do you think Nakano is referring to in his quote?

• A) peptide
• B) glycosidic
• C) phosphodiester
• D) ionic
