In 1962, three scientists who contributed to the discovery of the structure of the DNA molecule were awarded the Nobel Prize in Physiology and Medicine. The fourth scientist who contributed to this discovery, Rosalind
Franklin, was not awarded the prize, as she had died before this honor could be bestowed. ( What was her major
contribution to this discovery? )

- she determined that DNA was a crystal

- she captured the X-ray crystallography image that led to the discovery

- she determined that nitrogenous vases occurred in pairs

- she determined DNA was a double helix

How do water’s relative densities as a solid and a liquid differ from that of most other substances? water’s solid and liquid forms have different densities, while most other substances have solid and liquid forms with similar densities. water’s solid and liquid forms have similar densities, while most other substances have solid and liquid forms with different densities. water’s liquid form is less dense than its solid form, while the opposite is true of most other substances. water’s solid form is less dense than its liquid form, while the opposite is true of most other substances.
