WebSubsequent studies in many organisms showed that the double helical structure of DNA, the mode of its replication, and the genetic code are the same in virtually all organisms, including plant s, animal s, fungi, bacteria, and virus es.

WebIn 1928, British bacteriologist Frederick Griffith conducted a series of experiments using Streptococcus pneumoniae bacteria and mice. Griffith wasn't trying to identify the genetic material, but rather, trying to develop a vaccine against pneumonia. In his experiments, Griffith used two related strains of bacteria, known as R and S.

By using Chargaff's and Franklin's work, Watson and Crick made a tin and wire model of the double helix shape of DNA. They also created the basic rules of pairing. This means that a purine is always paired with a pyrimidine, meaning Adenine to Thymine and Guanine to Cytosine.
