Genes code for the production for proteins. Some of these are enzymes which control how the cell functions. This slideshow demonstrates how a protein is produced using the genetic code.How a protein is produced using the genetic code. Genes contain bases in groups of three. Page: 1  1. 2  2. 3  Next. gene is a section of DNA which controls part of a cell's chemistry-particularly protein production. is a shorter region of DNA that carries the genetic code for a particular characteristic or cell activity. Nucleus, chromosome and gene. DNA molecules contain chemicals called bases.
Limestone is calcium carbonate (CaCO3) which when heated to above 840Â°C decomposes into calcium oxide (CaO) while releasing carbon dioxide (CO2) according to the equation: CaCO3(s) â CaO(s) + CO2(g). CaO is commonly known as lime, quicklime, or burnt lime.
When limestone gets even more squashed, it can turn into travertine or marble. Limestone is also the main way you get lime, which is one of the things you make cement out of. To get lime, you have to burn limestone in lime kilns, and then what is left is lime. In the Middle Ages, people burned most of the statues of ancient Greece and Rome to turn them into lime.
