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.
Solar Wind's Effect on Earth. The Sun produces a solar wind â a continuous flow of charged particles â that can affect us on Earth.It can, for example, disrupt communications, navigation systems, and satellites. Solar activity can also cause power outages, such as the extensive Canadian blackout in 1989.he Sun produces a solar wind â a continuous flow of charged particles â that can affect us on Earth.
