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.
An example of a rain shadow. A rain shadow is a dry area on the lee side of a mountainous area (away from the wind). The mountains block the passage of rain-producing weather systems and cast a shadow of dryness behind them. The central region of Myanmar is in the rain shadow of the Arakan Mountains and is almost semi-arid with only 750 millimetres (30 in) of rain as against as much as 5.5 metres (220 in) on the Rakhine State coast.
