the termination event can be prevented by specific ancillary factors that interact with RNA and/or RNA polymerase, a situation referred to as antitermination.

Electrons are constantly are moving in an atom, so dipoles are probable of occurring.

A dipole is defined as molecules or atoms with equal and opposite electrical charges separated by a small distance.

There are four major DIPOLES that decide VWI

1. spontaneous (or instantaneous) dipoles

2. Dipole-Dipole Interaction

3. Induced Dipoles

4. Spontaneous Dipole-Induced Dipole Interaction

Spontaneous (or instantaneous) dipoles

When groups of electrons move to one end of the atom, it creates a dipole.
