The more researchers examine RNA, the more surprises they continue to uncover. What have we learned about RNA structure and function so far? Although RNA is a single-stranded molecule, researchers ...

In (+)-stranded RNA viruses, RNA is the sole genetic material. Because infected host cells ordinarily lack RNA-dependent RNA polymerase (RdRp) activity, these RNA viruses encode a replicative ...

This diagram depicts the chemical structure of pyrimidine, a six-membered aromatic ring with two nitrogen atoms at positions 1 and 3 (highlighted in blue). The remaining positions are occupied by ...
