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.
Cumulonimbus clouds have a layered effect, which is indicative of the cloud growth. The reach of the cloud extends from 1000 feet above the surface to more than 40,000 feet. Water vapor and updrafts within a cumulus cloud create the larger cumulonimbus as part of the thunderstorm cycle. Sometimes the anvil-shaped top of the cloud is visible before the lower part of the clouds, which appears as a wall. These clouds also produce winter storms, such as blizzards.
