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.

â¢ High-Calcium Limestone: â¢ Magnesian Limestone: Lastly, some dolomites contain an excess of magnesium (Mg) and are called magnesian dolomite or high-magnesium dolomite. The excess magnesium is probably in the form of magnesium carbonate minerals, of which magnesite (MgCO3) is a possible candidate.imestone, however, is very rarely pure calcite, pure dolomite, or a pure mixture of the two. It typically contains a variety of accessory rock materials of which quartz, chert, clay and pyrite are among the noteworthy.
