Orientation of strands

- the strands go from 5' - 3' OR 3' - 5' - See IMAGE !! Note the direction of the RNA Primer (shown to be <- 3' - 5') - extra note for fun: the 5' end has a free phosphate on a 5' carbon and the 3' end has a free phosphate on a 3' carbon (Remember how the carbon atoms in the sugar ring are number 1' to 5', like we learned in chemistry)
