Multiple Choice
Use the following information when answering the corresponding questions) .
Shuichi 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) ionic
C) glycosidic
D) phosphodiester
