The
hydroxyaldehyde shown cyclizes to form a hemiacetal under acidic or
basic conditions. Use wedge-dot structures to draw the two
stereoisomers formed from the aldehyde when it cyclizes. Explain if
the relationship between the products is the product mixture
expected to be optically active or optically inactive.

draw a monomer of DNA, label all parts and the carbon numbers on the sugar. The way to number the carbons in the sugar is to start at oxygen and number each carbon with the base attached at carbon 1. Now draw a monomer of RNA. Label all parts and number the carbons in the sugar. compare the two drawings by writing differences below. Now draw a diner of either DNA or RNA and show how two nucleotides are connected
