the sides of a double helix are composed of a chain alternating between a phosphate and a deoxyribose (5 carbon) sugar.

Phosphate and sugar.
The sides of the DNA double helix ladder is composed of alternating phosphate groups and deoxyribose sugars.
-Two helices
If you mean the "rungs", they are made up of the bases (adenine and thymine; cytosine and guanine). The sides of the double helix is made up of phosphate and sugars.
DNA is a double helix made of two strands linked together with hydrogen bonds.
altering sugar parts and phospate parts
The sides of the ladder of the double helix are made of groups of hydrogen bonding between the purines and pyrimidines. The backbone is made up of sugar-phosphate.
The Double helix is actually made of repeating units called nucleotides
