As with other chemical reactions, the reaction rate and efficiency of PCR are affected by limiting factors. 1  Thus, the entire PCR process can further be divided into three stages based on reaction progress: 2  Exponential amplification: At every cycle, the amount of product is doubled (assuming 100% reaction efficiency).
Quick Answer. Aquamarine forms when magma under the Earth's crust interacts with mineral-rich rocks under mountain ranges. The magma cools as it enters fissures and crevasses of rocks called pegamites. The minerals in the pegamites heat up when they interact with the magma, forming the gemstone. Continue Reading.
