functional difference between 70S and 80S RNA

Post by justcurious91 » Wed Oct 06, 2010 8:34 pm

RNA in both eukaryotes and prokaryotes have a similar function of synthesizing proteins and the mechanism for synthesis, elongation and proof reading is also similar. so why is there a difference in their sedimentation number? ( 80S for eukaryotes and 70S for prokaryotes).

the difference is in the evolutionary history. Look e.g. to the DNA/RNA Pols and the difference between them

Cis or trans? That's what matters.
