Lesson: DNA Biology

Students will be able to

• describe the structure of DNA as a polymer made up of repeating monomer subunits called nucleotides,
• describe how the two strands of DNA form a double helix shape, with a sugar–phosphate backbone,
• explain that the double helix shape is maintained by the complementary base pairings (A to T and C to G),
• describe the structure of a nucleotide as a central deoxyribose sugar bonded to a nitrogenous base and a phosphate group,
• state DNA that is read in the 5’ to 3’ direction,
• explain how DNA can be extracted from organic material, such as fruit.
