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.
There are three different ways of turning moist air into cloud, so that it rains or snows. Rain-and other forms of precipitation-occur when warm moist air cools and condensation occurs. Since warm air can hold more water than cool air, when the warmer air is cooled the moisture condenses to liquid-and it rains. The video and text below explain how rain forms and the different types of rain that we get in the UK.
