RS Configuration 

Atoms of higher atomic number rank above those of lower atomic number (e.g., —OH ranks above —CH3). If the first substituent atoms are identical, the priority is established by the next atom outward from the chiral center (e.g., —CH2OH takes precedence over —CH3).

#Unit 3. Fundamental Processes

Dicer will act on any dsRNA, regardless of sequence, and will cleave this molecule 22 nucleotides from its end.  The PAZ domain anchors the 3’ terminus of the substrate RNA to position the active sites of the enzyme 22 nucleotides away in a ruler-like fashion
