A field of biology which studies the structure and function of genes at a molecular level.

(quantum mechanics, chemistry) The quantum mechanical behaviour of an electron in a molecule describing the probability of the electron's particular position and energy; approximated by a linear combination of atomic orbitals.

(chemistry) The mass of an individual molecule of an element or compound.

(chemistry) The sum of the atomic weights of every atom in a molecule.
