RNA is single stranded, can hydrogen-bond with other nucleic acids, and has functional groups that can function in catalysis. These characteristics support that RNA could have which of the following cellular roles?
A) tagging proteins for degradation by lysosomes
B) targeting proteins for secretion
C) forming scaffolds for ribosome attachment
D) forming peptide bonds

Question

Quizplus · Accepted Answer

RNA's ability to catalyze reactions, such as forming peptide bonds, is exemplified by ribozymes, which are RNA molecules with catalytic activity. This supports the role of RNA in forming peptide bonds during protein synthesis in the ribosome.
