Question
Choose the one most appropriate answer for each.
Avery and McCarty
Rosalind Franklin
Fred Griffith
Hershey and Chase
Friedrich Miescher
the first to demonstrate, through the use of radioactive isotopes, that DNA, not protein, was the substance transmitted through generations of cells
discovered that the hereditary system of one strain of bacteria could be transformed by materials from another strain of bacteria
obtained excellent X-ray diffraction photographs that suggested that DNA was a long, thin molecule with regularly repeating structures; also said that DNA had to be helical like a circular stairway
in 1944, reported that DNA was the "transforming principle"
first to discover DNA and isolate it from fish sperm

Explanation / Answer
Avery and McCarty: in 1944, reported that DNA was the "transforming principle"
Rosalind Franklin: obtained excellent X-ray diffraction photographs that suggested that DNA was a long, thin molecule with regularly repeating structures; also said that DNA had to be helical like a circular stairway
Fred Griffith: discovered that the hereditary system of one strain of bacteria could be transformed by materials from another strain of bacteria
Hershey and Chase: the first to demonstrate, through the use of radioactive isotopes, that DNA, not protein, was the substance transmitted through generations of cells
Friedrich Miescher: first to discover DNA and isolate it from fish sperm
Avery and McCarty, Rosalind Franklin, Fred Griffith, Hershey and Chase and Friedrich Miescher are well known for their discoveries in Molecular biology. They have done enormous research on genetic material, especially on DNA and provided the vital information to the future generation.
