Question

RNA secondary structure is composed primarily of triple-stranded RNA regions formed by folding the single-stranded molecule back twice on itself.

(a) True

(b) False

This question was posed to me in exam.

I want to ask this question from Limitations of Prediction in section RNA Structure Prediction of Bioinformatics

Answer 1

Correct choice is (b) False

To elaborate: RNA secondary structure is composed primarily of double-stranded RNA regions formed by folding the single-stranded molecule back on itself. To produce such double-stranded regions, a run of bases downstream in the RNA sequence must be complementary to another upstream run so that Watson–Crick base-pairing between the complementary nucleotides G/C and A/U (analogous to the G/C and A/T base pairs in DNA) can occur.
