DNA replication of Eukaryotes (cells with a nucleus) occurs stepwise. Each step needs different enzymes. The DNA replication steps can be broken down as: A notch is made by DNA gyrase. This looks like a bubble under a microscope, called Replication Bubble. Cracking up the hydrogen bonds in the double helix is the vital step and it occurs where more A-T bases exist.
Walking - or doing any effort with our muscles with that matter - converts chemical energy into mechanical energy. We get the chemical energy from the food we eat.

Electric energy is then converted to useful mechanical energy by motors. And mechanical energy is converted to electrical energy by electric generators. The Energy Story is a good website that describes what energy is. How energy and work are related.nergy Conversion. Definition: The process of changing one form of energy into another. For example, the chemical energy in gasoline can be converted into kinetic energy (energy of motion) by an automobile engine. Definition obtained from the K - 12 Energy Education Program (KEEP).
