Which of the following is FALSE about nucleotides?
   Adenine binds to thymine with two hydrogen bonds
   Uracil is unique to DNA
   Adenine binds to thymine with two hydrogen bonds
   Guanine binds to cytosine with three hydrogen bonds

Solution

The statement - \"Uracil is unique to DNA\" is false.

Uracil is one of the four nucleotide bases in the nucleic acid of RNA that are represented by the letters A, G, C and U. The others are adenine (A), cytosine (C), and guanine (G). In RNA, uracil binds to adenine via two hydrogen bonds. In DNA, the uracil nucleotide base is replaced by thymine. Uracil is a demethylated form of thymine.
