The two-dimensional structures of mRNA, tRNA, and rRNA are shown in the diagrams.
Which of the following might be one contributing factor to the function of rRNA based on comparisons between the structures of the three molecules?
A - rRNA molecules are sufficiently flexible because they contain more RNA loops.
B - rRNA molecules are more reactive because they have longer chains of unmatched bases.
C - rRNA molecules are sufficiently stable because the sequence of bases allows for more internal hydrogen bonds.
D - rRNA molecules are more rigid because they have a more regular sequence of bases than other RNA molecules.
