Combinations of these atoms form the sugar-phosphate backbone of the DNA -- the ... made along the way -- in other words, that a base pair in one DNA molecule doesn't match the corresponding ...

Erwin Chargaff's groundbreaking research, which showed that DNA base pairs had a complementary relationship, laid the foundation for James Watson's and Francis Crick's DNA model. When word spread that ...

DNA is the molecular basis of heredity ... the sugars and phosphates form a "backbone," along which the base pairs are strung. Fully assembled, the sequence of base pairs is a compound molecule ...
