Van der Waals Forces and Their Biological Significance

What is the primary characteristic of van der Waals forces?

• They are responsible for the color of molecules.

• They are the main forces holding atoms together in a molecule.

• They are weak attractive forces between charged particles.

• They are strong covalent bonds.

Which scientists are credited with discovering the double helix structure of DNA?

• Einstein and Newton

• Watson and Crick

• Curie and Rutherford

• Darwin and Mendel

What is the role of hydrogen bonds in the structure of DNA?

• They form the backbone of the DNA strand.

• They connect the base pairs in the DNA double helix.

• They provide energy for DNA synthesis.

• They are responsible for the replication of DNA.

How do geckos use van der Waals forces to walk on smooth surfaces?

• By secreting a special adhesive

• By using suction cups on their feet

• By having sticky pads on their toes

• By having millions of microscopic hairs on their feet

In what way are van der Waals forces similar to ionic bonds?

• Both are strong chemical bonds.

• Both involve attractions between charged particles.

• Both are responsible for the color of compounds.

• Both involve the sharing of electrons.
