Describe the structure of DNA, using appropriate terminology.
A nucleotide is the monomeric building block of the polymer of DNA. To better understand the characteristics
of DNA, it is important to understand how the monomers join to form the polymer. Use the following diagram
of DNA (and the diagram of a nucleotide in the PowerPoint presentation) to label the listed features: 3' and 5'
ends, nucleotide, phosphate group, sugar group, phosphodiester bond, nitrogenous base (pyrimidine and
purine), and hydrogen bonds.

NH2
HN
OH₂N
NH₂
5. Looking at the polymer, why is a DNA
considered antiparallel?
6. Why are the ends of DNA strands
named 3' or 5'?
7. How do A:T interactions differ
compared to G:C interactions? How does
this affect stability of the bond pairs?
8. During gel electrophoresis, to which
electrode (+ or -) does DNA migrate?
Why?
