DNA and RNA are nucleic acids.
Explain why RNA can be described as a polymer and as a macromolecule.
The sugar component of DNA is a reducing sugar.
Outline the test for reducing sugars and describe the observations for a positive result.
Nucleotides are structural components of nucleic acids. Each nucleotide consists of a pentose sugar, a phosphate group and a nitrogenous organic base.
Complete Table 1 to compare DNA nucleotides with RNA nucleotides as structural components of nucleic acids.
