• How do purines and pyrimidines differ? Name two of each type in DNA.
• Show how nucleotides are linked together to form a nucleic acid strand.
• Show how the two antiparallel and complementary strands of DNA are arranged...draw a double helix with three base pairs.
• How is the double helix complexed with proteins to form nucleosomes and solenoids?
• How are these structures arrayed to form a metaphase chromosome?
