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.
Limestone is fed into the upper or back end of the kiln, while fuel and combustion air are fired into the lower or âfront endâ of the kiln. The limestone is heated as it moves down the kiln toward the lower end. As the preheated limestone moves through the kiln, it is âcalcinedâ into lime. The lime is discharged from the kiln into a cooler where it is used to preheat the combustion air. Lime can either be sold as is or crushed to make hydrated lime.
