Question

A DNA segment rich in guanine-cytosine pairs tends to be more stable than segments rich in adenine-thymine pairs. Which statement best explains this phenomenon?

Accepted Answer

Guanine-cytosine pairs form three hydrogen bonds, whereas adenine-thymine pairs form two.

Answer

Guanine-cytosine pairs form two hydrogen bonds, whereas adenine-thymine pairs form three.

Answer

The ionic strength of guanine-cytosine bonds is greater than that of adenine-thymine bonds.

Answer

Guanine-cytosine pairs form covalent bonds, whereas adenine-thymine pairs form hydrogen bonds.
