What was Watson and Crick's main scientific accomplishment?

• Building the first accurate model of DNA
• Isolating strains of pneumonia causing bacteria
• Determining base pairing rules
• Discovering the process of genetic transformation

Who was responsible for the model shown?

• Oswald Avery
• Watson and Crick
• Erwin Chargaff
• Rosalind Franklin

Who is responsible for producing this image?

• Francis Crick
• James Watson
• Rosalind Franklin
• Watson and Crick

Who worked in the same lab as Rosalind Franklin

• Francis Crick
• James Watson
• She only worked solo
• Maurice Wilkins

How did Rosalind take pictures of the shape of DNA

• X-Ray diffraction
• X-Ray microscopy

Why didn't Rosalind Franklin at least receive a part of the Nobel Prize for the discovery of DNA?

• She was deemed unworthy.
• Winners have to be alive in order to be awarded the prize
• She did not receive enough nominations.
