For the software package, see Partition function for Interacting RNAs. Piwi-interacting RNA (piRNA) is the largest class of small non-coding RNA molecules expressed in animal cells. piRNAs form RNA-protein complexes through interactions with piwi proteins.
RNA (ribonucleic acid) is a single strand with 5-carbon sugar that has one more oxygen than DNA. The nucleotides in RNA pair Adenine To URACIL, Guanine to Cytosine, and Thymine to Adenine (These pairings happen when the RNA is copying the DNA).4 people found this useful.NA (ribonucleic acid) is a single strand with 5-carbon sugar that has one more oxygen than DNA.
