    Transfer RNA uses adenine, guanine, uracil, and cytosine while messenger RNA uses adenine, guanine, thymine, and cytosine.

    B

    Transfer RNA uses adenine, guanine, thymine, and cytosine while messenger RNA uses adenine, guanine, uracil, and cytosine.

    C

    Transfer RNA has a complex loop structure while messenger RNA is usually a simple, linear strand.
