Sequence the following events that led to our understanding
     Sequence the following events that led to our understanding of DNA in chronological order.  The human genome was sequenced.  X-ray diffraction revealed the 3D shape of DNA.  A harmless bacterial strain found to cause disease after receiving DNA (not protein) from another bacterial strain.  A model of DNA was created showing how its subunits form is double-helical shape.  Viruses labeled with radioactive phosphorous injected their DNA into bacteria.   
  
  Solution
A harmless bacterial strain found to causedisease after recieving DNA (not protien) from another bacterial strain -...................... experiment by Avery, McCarty, and MacLeod: Identifying the transforming principle (1944)
Viruses labelled with radioactive phosphorus injected their DNA into bacteria..........(Hershey-Chase experiments 1952)
A model of DNA was created showing how its subunits form its double helical shape .......... (Watson & Francis crick, 7 march, 1953)
X-ray diffraction revealed the 3D shape of DNA.......(Rosalind Franklin April 1953, acta crystallographica)
Human genome was sequenced ......(April 2003)
