Individual codons code for specific amino acids. A gene is a sequence of nucleotides along a DNA strand-with 'start' and 'stop' codons and other regulatory elements-that specifies a sequence of amino acids that are linked together to form a protein.ndividual codons code for specific amino acids.

Dolomites. Italy's dramatic rocky rooftop, the Dolomites, offers some of the best mountain thrills in Europe. The bold, light-gray cliffs and spires flecked with snow, above green meadows and beneath a blue sky, offer a powerful, unique, and memorable mountain experience.olomites.

Calcite and Dolomite: Carbonate Minerals Calcite and dolomite are very similar minerals. Both have the same hardness (H = 3), the same rhombohedral cleavage, and are found in identical geologic settings.The best way to tell one from the other is the acid test: a drop of 1 M HCl on calcite produces an instant, obvious fizz; a drop on dolomite produces slow or no obvious bubbling.Frequently, you have to use a knife point to powder a small area of dolomite to get a visible reaction to a drop of acid.he best way to tell one from the other is the acid test: a drop of 1 M HCl on calcite produces an instant, obvious fizz; a drop on dolomite produces slow or no obvious bubbling.
