There are 20 isotopes of sodium ( 11 Na), ranging from 17. Na to 39. Na (except for the still-unknown 36 Na and 38 Na), [ 4] and two isomers ( 22m. Na and 24m. Na ). 23. Na is the only stable (and the only primordial) isotope. It is considered a monoisotopic element and it has a standard atomic weight of 22.989 769 28(2).

RNA polymerase II ( RNAP II and Pol II) is a multiprotein complex that transcribes DNA into precursors of messenger RNA (mRNA) and most small nuclear RNA (snRNA) and microRNA. [ 1][ 2] It is one of the three RNAP enzymes found in the nucleus of eukaryotic cells. [ 3] A 550 kDa complex of 12 subunits, RNAP II is the most studied type of RNA ...
