The advances in genetic engineering. [3] Herb Boyer studied bacteria in a California hospital; one morning he found a bacteria that could splice DNA, with enzymes (a restriction endonuclease); in March 1973 Boyer and Stanley Norman Cohen worked on an experiment to put a toad gene into a bacteria; the experiment worked, and the bacteria cell produced toad proteins; Paul Berg, of Stanford ...
Rosalind Franklin joined King's College London in January 1951 to work on the crystallography of DNA. By the end of that year, she established two important facts: one is that phosphate groups, which are the molecular backbone for the nucleotide chains, lie on the outside (it was a general consensus at the time that they were at the inside); and the other is that DNA exists in two forms, a ...

Two categories of macromolecules in particular are the focus of the molecular biologist: 1) nucleic acids, among which the most famous is deoxyribonucleic acid (or DNA), the constituent of genes, and 2) proteins, which are the active agents of living organisms. One definition of the scope of molecular biology therefore is to characterize the ...

[3] [4] Within a few days, Watson and Crick were able to build their famous model for DNA. [5] In their famous article by Watson and Crick in Nature that proposed the structure of DNA, the following acknowledgment to Donohue appears: "We are much indebted to Dr. Jerry Donohue for constant advice and criticism, especially on interatomic ...
