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.
Raindrops keep fallinâ. Swirling winds inside clouds may be one of the keys to quick formation of raindrops. [Credit: ]Ã. Although the TV weatherman can say where raindrops might fall, researchers still have difficulty explaining why they form. A paper in the 26 March PRL sheds light on this cloudy subject by showing that wind turbulence can play a crucial role.
