Exploring Genetics in Greatest Discoveries

What was the main focus of Alfred Hershey and Martha Chase's research?

• The behavior of bacteria

• The genetic material in viruses

• The structure of proteins

• The function of ribosomes

What did Hershey and Chase use to label the protein and DNA in their experiments?

• Radioactive chemicals

• Enzymes

• Magnetic particles

• Fluorescent dyes

What was the significant finding of Hershey and Chase's experiment?

• Proteins carry genetic information

• DNA carries genetic information

• Viruses do not infect bacteria

• Bacteria can produce viruses independently

Who were the main scientists working on the structure of DNA at Cambridge University?

• Gregor Mendel and Thomas Hunt Morgan

• Maurice Wilkins and Rosalind Franklin

• James Watson and Francis Crick

• Alfred Hershey and Martha Chase

What technique did scientists use to infer the structure of DNA?

• Electron microscopy

• X-ray crystallography

• Nuclear magnetic resonance

• Mass spectrometry

What did Watson and Crick need to complete their DNA model?

• More funding

• More data

• More time

• More researchers

Who provided Watson and Crick with the crucial x-ray image of DNA?

• Rosalind Franklin

• Maurice Wilkins

• Martha Chase

• Alfred Hershey

What did Watson and Crick's model reveal about the structure of DNA?

• It is a single helix

• It is a double helix

• It is a triple helix

• It is a quadruple helix

What is the significance of the double helix structure of DNA?

• It allows DNA to be flexible

• It enables DNA to replicate

• It makes DNA resistant to damage

• It helps DNA to bind with proteins

Why was Rosalind Franklin not awarded the Nobel Prize along with Watson, Crick, and Wilkins?

• She refused the award

• She had passed away

• She was not a biologist

• She did not contribute to the discovery
