The History of DNA as Genetic Material
Genetic material has to satisfy 3 criteria. Genetic material must be able to encode (1) used by the cells to code for RNA or Proteins. Genetic Material needs to be (2) with a high level of accuracy to maintain the integrity of the original code. This genetic material must also be able to pass along to new cells via (3) when cells undergo cellular division or when a foreign entity infects the cells. The unity and diversity of life illustrated how organisms have descended from a common ancestor and through modification and (4) of the genetic code, we now have all of the many species and organisms that belong to the biosphere today.
In 1940, (16) expanded on the previous research. The DNA from the smooth bacteria was (17). Five samples were created. The (18) test tube contained only the Rough bacteria, which would not grow on the petri dishes. The second test tube contained smooth DNA + rough bacteria, (19) occurred and once plated on the petri dishes colonies grew. In the third test tube, smooth DNA + rough bacteria+ (20) added and no colonies grew on the petri dish. In the fourth test tube smooth DNA + rough bacteria+ (21) knocking out ribonucleic acid function was added and colonies grew on the petri dish. In the fifth test tube smooth DNA + rough bacteria+ (22) thus preventing protein production and colonies grew on the petri dish. This experiment shows that in test tube 3, no colonies grew because smooth strain (23) was blocked/destroyed by (24). Thus (25) is the transforming principle.
