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.

Mechanical energy is the energy possessed by an object due to its motion or its position. Well, that seems simple enough, but what is energy? Energy is the ability to do work, where work is the movement of an object when a force is applied to it. For example, a person doing push-ups is doing work by applying force to the floor.
