They combine with proteins to form
Their ds type is cleaved by the dicer enzyme and added to RISC, in a pathway named for one type of these molecules. They combine with proteins to form snRNPs ["snurps"], five of which make up a spliceosome. One type is bounded by a poly-A tail, while another type containing pseudo·uridine is cloverleaf-shaped. Retroviruses and ribosomes are made of these molecules. One type is produced in transcription, and another type performs translation. With messenger and transfer types, they contain uracil. For 10 points, name these single-stranded nucleic acids similar to DNA.
