Question

Unlike DNA, which is mainly double stranded, RNA is double stranded, although an RNA molecule can self-hybridize at certain regions to form partial double-stranded structures.

(a) True

(b) False

The question was posed to me by my school teacher while I was bunking the class.

My question comes from Types of RNA Structures in portion RNA Structure Prediction of Bioinformatics

Answer 1

Right answer is (b) False

For explanation: RNA is single stranded, although an RNA molecule can self-hybridize at certain regions to form partial double-stranded structures. Generally, mRNA is more or less linear and non-structured, whereas rRNA and tRNA can only function by forming particular secondary and tertiary structures.
