An experiment was conducted on a bacterial DNA strand by exposing it to high-temperature conditions. Determine which sections would most probably consist of larger amounts of guanine-cytosine (GC) pairings and which ones would consist mainly of adenine-thymine (AT) pairings.

The sections where separation occurs rapidly should be rich in guanine-cytosine (GC)

The parts remaining closely bonded even after exposure should mostly comprise guanine-cytosine (GC)

The parts remaining closely bonded even after exposure should mostly comprise adenine-thymine (AT)

All parts will equally comprise both types of bases
