18. James Watson and Francis Crick discovered that hydrogen bonds form
between nitrogenous bases in the DNA molecule. Why was this discovery
important to understanding how DNA replicates?
F
Hydrogen bonds form the sugars that make up the backbone of the DNA molecule.
G.
Hydrogen bonds connect the sugar of one nucleotide to the phosphate group of the next.
H. Hydrogen bonds can link any two DNA nucleotides together
J. Hydrogen bonds make it possible for the two DNA strands to separate.
