In 1944-1950 , Erwin Chargaff discovered that guanine and cytosine units, as well as adenine and thymine units, were the same in double-stranded DNA, and he also discovered that the DNA varies among species.
Wow!, the bases have equal units and there is a variety among species.
In 1952, Alfred Hershey and Martha Chase discovered that DNA, and not protein, was the genetic material in bacteriophage, a discovery based on evidence from the legendary "blender experiment"
It seems that DNA was never a protein
BIBLIOGRAPHY:
In 1951, Rosalind Franklin to ok the first image using X-Rays of the DNA, were it revealed the helical shape of the DNA molecule, which led to the discovery of
I CAN'T BELIEVE IT ! THIS IS WHAT A DNA STRUCTURE TRE LOOKS LIKE
In 1953, James Watson and Francis Crick discovered the molecular structure of the DNA,
WE HAVE DISCOVERED THE SECRET OF LIFE
