<u>Griffith Experiment 1928</u>
When Frederick Griffith's experiment of transformation in 1928 concluded the fact that DNA formula can be transferred through bacteria and the process is known as transformation.
Griffith used two strains of Streptococcus Pneumoniae: type III-S (smooth) and type II-R (rough) strain. He first injected the type III S bacteria into mice that caused its death.
Then he injected type II R strain that didn't affect its life. He then used a heat-killed S bacteria that also failed to kill the mice. Now, he used a combination of heat-killed S bacteria and type II R strain which proved to be deadly for the mice.
He was able to get both types of strains from the tissues of the dead mice which became the core of the transformation concept concluded that while using the combination of type II R and heat-killed S bacteria, DNA properties of type II R got converted into type III S bacteria that caused the death of the mice and remained distinguishable in the tissues i.e. it might further cause the death of other mice. This was termed as the Transformation Process.

Answer:
The Americans helped the British Empire, French and Portuguese forces defeat and turn back the powerful final German offensive (Spring Offensive of March to July, 1918), and most importantly, the Americans played a role in the Allied final offensive (Hundred Days Offensive of August to November).
