Description:
- Biochemist Erwin Chargaff discovered a link between the proportions of bases in DNA and the species the DNA had come from- He also discovered that the amount of adenine (A) and the amount of thymine (T) in the DNA were always equal.
- He also found that the amount of cytosine (C) and the amount of guanine (G) in the DNA were always equal.
