The methods that structural biologists use to determine their structures generally involve measurements on vast numbers of identical molecules at the same time.

A homo-trimer would be formed by three identical molecules.

However, if the underlying core is symmetrical, some of these choices will give identical molecules.

The number 15 was factored using 10 identical molecules, each containing seven active nuclear spins.

For the most part, scientists have been able to study many identical molecules folding together en masse.

Each can serve as a template for building a new identical molecule.

A homo-dimer would be formed by two identical molecules (process called homodimerization).

Heat it again with an excess of primers, and you can repeat the process, and two identical molecules will be replaced by four.

This works really well with a population of identical molecules.

To do that, you take a lot of identical molecules called amines and join them together to form a chain.
