  1. Question 1

    Q1. While RNA is generally single-stranded, one specific type folds into a clover-leaf shape with localized base pairing. Identify this molecule.

    • A) mRNA
    • B) rRNA
    • C) snRNA
    • D) tRNA

    Answer: tRNA

    Explanation: tRNA has specific regions of double-strandedness due to internal base pairing. mRNA is tempting because it is RNA, but it remains strictly single-stranded and linear.
