Nirenberg and Matthaei studied the role of RNA in protein synthesis, specifically in the bacteria E. coli.

James Watson created an accurate model of the structure of DNA.

Watson and Crick proposed the poly nucleic model, stating that DNA and RNA were composed of nucleotides.

Chargaff concluded that, in DNA, adenine levels were equal to thymine levels and cytosine levels were equal to guanine levels.

Explanation:

1. Both Nirenberg and Matthaei studied the central role of RNA in protein synthesis is illustrated by the fact that many antibiotics used to fight infections bind to the ribosomal RNA of bacteria and block the production of cellular protein. This prevents the bacteria from growing.

2. In the spring of 1953, Watson saw that the essential DNA components—four organic bases—must be linked in definite pairs.

This discovery was an important factor that enabled Watson and Crick to formulate a molecular model for DNA—a double helix, which can be likened to a spiralling staircase or a twisting ladder.

3. James Watson and Francis Crick postulated the “double helix” molecular structure of DNA. Each DNA strand, in this case, is linear and long and is made up of smaller units known as nucleotides that link together to form a chain.

4. Chargaff's rules state that in the DNA of any species and any organism, the amount of guanine should be equal to the amount of cytosine and the amount of adenine should be equal to the amount of thymine.
