Title: Comparison of RNA and DNA
Description: This table gives a comparison that is good for any level from 1st year to senior. It shows the difference between the types of sugar, nitrogen bases, the function, and shape of the molecule along with examples of how the base pairing works (base-to-base).

along the length of the strand; three
main types (mRNA, rRNA, tRNA)
Pared strands coiled in a double
helix
