draw a monomer of DNA, label allparts and the carbon numbers on the sugar (as shown in figure 2.18but the goal is to draw without help). The way to number the carbons in the sugar is to start atnumber the carbon at which the base is attached as 1 and thenmoving away from the oxygen number sequentially.

Now draw a monomer of RNA. Again, label allparts and number the carbons in the sugar. Comparethe two drawings by writing differences below.

Now draw a dimer of either DNA or RNAand show how two nucleotides are connected (refer to figure 3.7 and3.18 for help). This ameba sisters gif might help too.
