An enzyme called helicase breaks the bond between nitrogeneous base, where the two strand of DNA split.
Energy sources are classified as nonrenewable because they do not form or replenish in a short period of time. Renewable energy sources such as solar and wind replenish naturally in a short period of time.
The four major nonrenewable energy sources are
<span>- Crude oil
- Natural gas
- Coal
- Uranium (nuclear energy) </span>
Nonrenewable energy sources come out of the ground as liquids, gases, and solids. We use crude oil to make liquid petroleum products such as gasoline, diesel fuel, and heating oil. Propane and other hydrocarbon gas liquids, such as butane and ethane, are found in natural gas and crude oil.
