DNA Timeline/ Model Project
Objectives:
 1. Construct a timeline of scientists and their contributions to the discovery
of the structure and function of the DNA molecule (30 pts)
 2. Construct a model of DNA, using any materials, that is at least 12 base
pairs long.
For objective 1, include the following scientists: (3 pts for each scientist)
Gregor Mendel
Friedrich Miescher
Frederick Griffith
Oswald Avery
Erwin Chargaff
Rosalind Franklin
Alfred Hershey and Martha Chase
James Watson and Francis Crick
Frances Crick (Central Dogma Idea)
Marshall Nirenberg
Write 3-4 good sentences (IN YOUR OWN WORDS) describing each scientist’s
contribution to the discovery of the structure and function of DNA
