  In chromosomes in the nucleus
• What are the building blocks of DNA called?

  Nucleotides
• What are the three main parts of a nucleotide?

  Phosphate group, sugar molecule, base
• How many different bases are found in DNA?

  Four
• What are the four bases in DNA?

  A, C, G, and T
• What remains constant in the structure of DNA nucleotides?

  Phosphate group and sugar molecule
• Which bases pair together in DNA?

  C pairs with G, A pairs with T
• If given a nucleotide sequence of one DNA strand, what can you determine about the opposite strand?

  You can deduce the complementary nucleotides
