Here, an enzyme such as DNA polymerase catalyzes a reaction in a first step and then checks that the product is correct in a second step. This two-step process results in average error rates of less than 1 error in 100 million reactions in high-fidelity mammalian polymerases.ere, an enzyme such as DNA polymerase catalyzes a reaction in a first step and then checks that the product is correct in a second step.

The correct answer is Mountains. Mountains can alter wind flow and create a rain shadow effect. A mountain is a large landform and is high surrounding a limited area. It is generally steeper and higher than a hill. Comments.
What Is The Rain Shadow Effect? Often times, mountains stand as barriers preventing precipitation from falling over certain areas. The Tibetan Plateau in China can be considerably arid due to the rain shadow effect it receives from the massive Himalayas rising nearby. Description Often times, mountains stand as barriers to clouds so as to prevent precipitation from falling on certain sides of them.
