What is the purpose of these? What are they used for?

1800s – DNA was first isolated; Gregor Mendel conducted experiments with pea plants
1900s – Scientists began to believe that DNA might store genetic information
1929 – 3 Major components of DNA (Deoxyribose sugar (S), phosphate group (P), and nucleic acid (A,T,G,C) were identified
1953 – Watson, Crick, and Wilkins awarded the Nobel Prize for their discovery of the structure of DNA
