Dictionary » M » Molecule MoleculeDefinition noun, plural: molecules A tiny or a very small piece (of something). (biology or biochemistry) An extremely small particle or substance, especially at cellular or structural level, as a biomolecule. (physics and chemistry) The smallest unit of an element or compound, made up of two or more atoms held together by strong chemical bond.
In physics and chemistry, a molecule is an electrically neutral, group of atoms that can exist alone in free state while its characteristic properties are retained. The atoms comprising the molecule may be of the same kind (as in oxygen molecule made up of two oxygen atoms) or of different kinds (such as water molecule made up of oxygen and hydrogen). In biology, particularly in biochemistry, a molecule is used less strictly that it can also refer to any minute particle such as charged organic molecules or to substances (called biomolecules) produced and occur naturally in living organisms such as proteins, carbohydrates, DNA, etc.

Re: Any SOLID arguments against evolution?... volume does not mean larger mass, it is quite conceivable. “The Hemoglobin number,”-- that is the number of different ways you can arrange the molecules that form Hemoglobin. There are more ways to arrange them than there are atoms in the universe, but there are only 5 ways that work! What ...

Re: chemistry D-amphetaminesThe D refers to the optical activity of the molecule. Some organic compounds cause the polarization direction of plane-polarized light to rotate. D compounds (from dextro, or right) are those that rotate the polarization plane clockwise when viewed ...

Calculating DNA concentration in PCR productwell a good rule of thumb is 2^n where n is number of cycles (provided you have a single dsDNA molecule to start with). so after 10 cycles e.g. 1024 molecules, but i don't know if that is sufficient for you...
