Question

Which of the following is not a base of RNA?

(a) Thymine (T)

(b) Adenine (A)

(c) Cytosine (C)

(d) Guanine (G)

I had been asked this question in an international level competition.

This interesting question is from Types of RNA Structures topic in division RNA Structure Prediction of Bioinformatics

Answer 1

Right option is (a) Thymine (T)

To explain I would say: RNA structures can be described at three levels as in proteins: primary, secondary, and tertiary. The primary structure is the linear sequence of RNA, consisting of four bases, adenine (A), cytosine (C), guanine (G), and uracil (U).
