P.A. Levene- Nucleotides
Levene characterized the different forms of nucleic acid, DNA from RNA, and found that DNA contained adenine, guanine, thymine, cytosine, deoxyribose, and a phosphate group. -
Frederick Griffith
A British bacteriologist whose focus was the epidemiology and pathology of bacterial pneumonia. Frederick's experiment suggested that bacteria are capable of transferring genetic information through a process known as transformation. He showed that a bacteria could transform from one strain into a different strain. This was later identified as DNA. -
Linus Pauling
Linus Pauling was one of the founders of the fields of quantum chemistry and molecular biology. -
Oswald Avery
A Canadian-born American physician and medical researcher. Discovered that DNA is the material of which genes and chromosomes are made. -
Erwin Chargaff
Erwin Chargaff discovered two rules that helped lead to the discovery of the double helix structure of DNA. He discovered that the amounts of adenine and thymine in DNA were roughly the same, as were the amounts of cytosine and guanine. -
Hershey and Chase
Alfred Hershey and Martha Chase that helped to confirm that DNA was the genetic material. In their experiments, they showed that when bacteriophages, which are composed of DNA and protein, infect bacteria, their DNA enters the host bacterial cell, but most of their protein does not. -
Rosalind Franklin
A British biophysicist and X-ray crystallographer who made critical contributions to the understanding of the fine molecular structures of DNA, RNA, viruses, coal, and graphite.Franklin is best known for her work on the X-ray diffraction images of DNA which led to discovery of DNA double helix. -
James Watson
James Watson is a co-discoverer of the structure of DNA in 1953 with Francis Crick. Discovered the molecular structure of nucleic acids and its significance for information transfer in living material -
Francis Crick
Francis Crick is a co-discoverer of the structure of the DNA molecule in 1953 together with James Watson. He was an important theoretical molecular biologist and played a crucial role in research related to revealing the genetic code. -
Maurice Wilkins
Maurice Wilkin's research contributed to the scientific understanding of phosphorescence, isotope separation, optical microscopy and X-ray diffraction, and to the development of radar. He is best known for his work with DNA.
