His point is that there are also molecular changes occurring which are not selected, because they have little or no effect on function.

These molecular changes weren't seen in participants who received treatments using the medium-grit hand piece, the researchers say.

His healing factor not only allowed him to survive the process, but also induced a molecular change in the metal.

"Not only molecular change, but also atomic, lad," said Simon.

Thus, there appears to be a complex set of molecular changes that occurs even before the fungus and host plant make contact.

The specific molecular changes involved in arrhythmias depend on the nature of the problem.

Such shock was productive of molecular changes in the cerebral cells.

Microwaves may cause dangerous molecular changes in milk, meat and fish.

Organismal, tissue, or cell level measurements of molecular dynamic changes over time.

The cellular and molecular changes hypothesized to take place following a seizure would only have effects lasting for minutes.
