One type of this molecule has a structure that can be explained using the "cloverleaf" model because it contains several loops.
This molecule's namesake interference was discovered by Andrew Fire and Craig Mello in their studies of C. elegans. One type of this molecule has a structure that can be explained using the "cloverleaf" model because it contains several loops. A 5-prime cap and poly A tail are added to another form of this molecule, which can undergo splicing. Uracil is found instead of thymine in this molecule. For 10 points, name this nucleic acid, which comes in transfer and messenger types, and has a different sugar base than DNA.
