-
Frederick Griffith
He discovered that DNA is inherited from the parents. This discovery shows that it is passed down from generations. -
Oswald Avery
He discovered that DNA is the structure that genes and chromosomes are made of. Helped other scientists see the basis and origin of the DNA molecule. -
Erwin Chargaff
He discovered the double helix in the DNA. This is a very important discovery that led to many other important biology discoveries. -
Alfred Hershey and Martha Chase
They found that only DNA is needed for viral replication. This can help scientists look at DNA and see what it is and what it can do. -
Watson and Crick
Discovered the DNA molecule structure. One of the most important scientific discoveries of all time in the biology world. This discovery is still making scientists ask questions. They met up with Rosalind Franklin and saw that she had figured out what they needed, so they quickly published their findings before her to get credit for the structure. -
Rosalind Franklin
She used X-ray diffraction to determine the shape of the DNA. The double helix is very important, her discovery is similar to Erwin's but, she used a different method.
