Because they are splitting to make more dna
A protein that is known as Helicase attaches to and breaks apart the hydrogen bonds that are between the bases on the DNA strands. Then it pulls the helix apart. DNA just works as a template to make mRNA (messenger RNA)
When a liquid or gas is heated, the molecules move faster, bump into each other, and spread apart. Because the molecules are spread apart, they take up more space. They are less dense. The opposite occurs when a liquid or gas is cooled.

The molecules in side move or spread apart
The part of a wave where molecules are spread out is called the trough. This is the lowest point of the wave, where the particles are farthest apart.
The molecules in a gas are spread further apart than those in a liquid.
Gas molecules are spread apart farther than solid molecules. They also have more energy, making them move faster
Liquid molecules are spread out. Solid molecules are close together. And gas molecules are far apart.
Yes. The molecules of a gas spread out to fill their entire container.
