3. Accomplishments (Cont.)
• Found out that hydrogen bonds could form between
certain nitrogenous bases, giving just enough force to
hold the two strands together
4. Their Research
• After Rosalind Franklin died, they found and added her
research to theirs, including her X-Rays of DNA
• They relied heavily on other scientists’ research
5. Their Research (Cont.)
• They made a model showing that hydrogen bonds could
create an almost perfect fit between the bases.
6. Their Inspiration
• They used Oswald Avery’s research to find out DNA’s
structure
• Oswald concluded that bacteria could pass traits onto the
next generation
• Their research about the hydrogen bonds helped Erwin
Chargaff find out the pairs for the nitrogenous bases.
