Question

Use the following information to answer the question(s) below. A part of an mRNA molecule with the following sequence is being read by a ribosome: 5' CCG-ACG 3'(mRNA). The following charged transfer RNA molecules (with their anticodons shown in the 3' to 5' direction)) are available. Two of them can correctly match the mRNA so that a dipeptide can form. What type of bonding is responsible for maintaining the shape of the RNA molecule ionic bonding between phosphates hydrogen bonding between base pairs van der Waals interactions between hydrogen atoms peptide bonding between amino acids

Explanation / Answer

B. Hydrogen bonding between base pairs

Hydrogen bonding between base pairs. RNAs (not just tRNAs) have a tendency to fold over on themselves and form double stranded regions due to interactions between base pairs, the same way double stranded DNA is held together.
